Xenomorph Template - Pathfinder RPG

A xenomorph is a parasitic lifeform with a multi-stage life cycle. A queen lays a type of egg (called an ovomorph) that contains a creature (called a facehugger) that is able to disable and impregnate a host parent. The growing xenomorph (called a chestburster) inherits traits from its unwilling parent before ripping free (killing the host) and starting its own life. It then matures quickly. See Xenomorph Lifecycle below for more details.

Xenomorph Template

Creating A Xenomorph

"Xenomorph" is an acquired template that can be added to any living, corporeal creature of size Small or larger (referred to hereafter as the base creature). A xenomorph retains all the base creature's statistics and special abilities except as noted here.

CR: Depends upon the creature's total Hit Dice, as follows:

HD	CR
10 or less	+1
11-15	+2
16+	+3

Type: The creature's type changes to aberration. Unlike most templates, do recalculate HD (d8s), BAB (3/4 total HD), good Will saves. See additional notes below.

Hit Dice: Change all racial HD to d8s and convert HD from parent's class levels to racial d8 HD. In addition, xenomorphs gain a number of additional HD as noted below:

Size	Additional HD
Small or Medium	+1 HD
Large	+2 HD
Huge	+4 HD
Gargantuan	+6 HD
Colossal	+10 HD

Calculate BAB and saving throws, feats, and skills from new HD total.

Armor Class: Increase natural armor bonus based upon size, as follows:

Size	Natural Armor Bonus
Small	+3
Medium	+4
Large	+5
Huge	+6
Gargantuan	+9
Colossal	+13

Special Qualities and Defenses: A xenomorph gains blindsight 120 ft., darkvision 60 feet, scent, immunity to acid, and DR 1/adamantine (+1 per additional 5 HD). It retains any racial special qualities and defenses but loses any gained from class levels.

Acidic Spray (Ex) As immediate action, spray blast of acid on any creature damaging you in melee. The spray deals damage as noted below, split evenly between weapon and attacker (if weapon is unarmed strike or natural attack, full damage applies to attacker). A successful Reflex save halves the acid damage. The save DC is Constitution-based.

Size	Acid Damage
Small or Medium	1d4
Large	1d6
Huge	1d8
Gargantuan	2d6
Colossal	2d8

Hazardous Corpse (Ex) The squares occupied by your corpse (same size as your Space) are considered difficult terrain. Any creature or unattended object in or moving into the area automatically takes damage equal to your Acidic Spray damage per round. The area remains hazardous for 1 round per HD. This can damage the floor and even cause your corpse to fall through if it is sufficiently damaged.

Weakness: A xenomorph gains vulnerability to sonic attacks.

Speed: A xenomorph retains all the base creature's movement speeds. A xenomorph of Small or Medium size gains a Climb speed equal to land speed. Larger xenomorphs gain a Climb speed equal to half land speed.

Attacks: A xenomorph retains any gore, talon, or wing attacks posses by the base creature. It also gains a bite attack for every head it possesses. If it has front forelimbs, it gains up to 2 claw attacks; if the base creature possessed any claw attacks, those are retained (even beyond 2). If it did not possess one, it grows a tail and gains a sting attack; if the base creature possessed a sting attack, that is retained. It is possible to retain other attacks at DM's discretion, but perhaps at the expense of another. For example, retaining tentacles but losing claws.

Special Abilities: A xenomorph retains any racial special attacks but loses any gained from class levels. A xenomorph with claws gains grab as a special attack.

Spittle (Ex) 3/day—As standard action, spew acid as ranged touch attack with a range of 30 feet (no range increments). A creature struck takes 2d4 points of acid damage.

Abilities: Increase from the base creature as follows: Str +2, Dex +4, Con +2; reroll Int, Wis, and Cha as 3d6.

Languages: A xenomorph understands (but cannot speak) any languages of the base creature. It also gains telepathy (xenomorphs only) 100 ft.

Feats: A xenomorph gains Improved Natural Attack (bite) as a bonus feat.

Skills: A xenomorph has skill points equal to 4 + its Intelligence modifier. Racial class skills are Acrobatics, Climb, Escape Artist, Fly, Intimidate, Knowledge (pick one), Perception, Spellcraft, Stealth, Survival, and Swim.

Xenomorph Lifecycle

The xenomorph begins life as a facehugger inside an ovomorph egg (an object with hardness 15 and 30 hp). Inside the ovomorph, the facehugger is in stasis and can survive indefinitely. When a living creature comes within 30 ft. of an ovomorph, it opens and releases the facehugger on the next round. The facehugger tries to isolate a target and disable it so as to implant a chestburster embryo. After 2d4 hours the chestburster reaches maturity and rips itself free of the host (killing it). Over the next 1d4 days, the chestburster grows and matures into a basic body shape like a young adult of its host race. Adult xenomorphs then try to capture additional potential hosts and bring them back to the hive for impregnation by more ovomorphs.

Immature Xenomorphs

To create a xenomorph in the early stages of transitioning from chestburster to adulthood, apply the Young template to the adult form twice. To create a xenomorph that is in the late stages of transitioning from chestburster to adulthood, apply the Young template to the adult form once.

Host Age

A xenomorph spawned from a creature with age categories or one that has had the young template applied to it grows into the adult version of said creature. For example, a chestburster spawned from a wyrmling red dragon will grow into a xenomorph with the base statistics of an adult red dragon, whilst one spawned from a young bugbear will grow into a normal bugbear. If the chestburster is spawned from a race without racial HD (and thus without a standard stat block), such as humans, then ignore any young or old age-related adjustments to physical ability scores when creating the xenomorph.

Tactics

Xenomorphs prefer to use surprise and stealth to their advantage. When faced with a group, lone xenomorphs try to isolate a main target using distraction and lighting to its advantage. It will then systematically kill the members of the group one-by-one from stealth. When in large groups, xenomorphs prefer to attack in a coordinated ambush, using their agility to avoid being hit as they slaughter their targets en-masse.

Facehuggers stalk potential hosts and wait in ambush for prolonged periods of time, waiting until the potential host is isolated from its group or asleep, before latching on and impregnating it. Once it has implanted its embryo, a facehugger will quickly find a place where it can die out of sight, often leaving its victim unaware of what just happened.

Xenomorph Variations

Praetorian

The praetorian caste is larger and tougher than regular xenomorphs and serve as guardians to the hive and queen. If a queen is killed, a praetorian can even evolve into a queen. To create a praetorian, apply both the Xenomorph and Advanced templates to a creature.

Queen

The queen is the ruler of a given hive and much larger and smarter than the average xenomorph. To create a queen, apply the Xenomorph, Giant, and Advanced templates to a creature. It also has at least four claws.

Class Levels

The class levels of a host are converted into racial HD when the Xenomorph template is applied. However, theoretically a xenomorph could advance with class levels after birth. Rogue, Fighter, and Barbarian are obvious choices for advancement. Because they are telepathic and xenophobic, they have no verbal language. However, they does not mean they could not develop the ability to utilize vocalizations such as required for spellcasting.

Other Colors

The core xenomorph race possesses a sleek black carapace, dark as midnight. Unless otherwise specified the examples herein are of this core variety. However, there are other color xenomorph variants with different traits. In general, the different color versions share a homicidal rage and loathing toward the very existence of other colors and almost invariably fight to the death when they encounter each other. A hive of mixed colors would be an unusual situation indeed.

Blue

The blue xenomorphs have a navy blue carapace and are even more organized and less hostile than black xenomorphs. They are Lawful Neutral in alignment instead of Neutral. They do not receive Improved Natural Attack (bite) as a bonus feat; rather, they receive a bonus Teamwork feat.

Green

These xenomorphs have a deep dark green carapace and are all invariably venomous. They lose the Spittle ability, and their Acidic Spray functions as if they were one size category smaller. They gain, however, a poison injected through their tail stings.

Poison (Ex) Sting—injury; save Fort DC 1/2 racial HD plus Con modifier; frequency 1/round for 6 rounds; effect 1d2 Dexterity damage; cure 2 saves. The save DC is Constitution-based.

Orange

These xenomorphs have a sleek deeply orange-red carapace. Orange xenomorph body fluids are not acidic; instead, they are superheated. They lose immunity to acid and instead gain immunity to fire. Their Acidic Spray and Spittle abilities replace acid damage with fire damage.

Purple

These xenomorphs possess an almost metallic purple carapace. Their jaws are not as powerful as standard xenomorphs, but their claws are far longer and sharper. They do not receive Improved Natural Attack (bite) as a bonus feat; rather, they receive Improved Natural Attack (claws).

Red

The red xenomorphs possess a deep crimson carapace but are otherwise physically identical to black xenomorphs. Socially, they are even more aggressive and are Chaotic Neutral in alignment instead of Neutral. Instead of the Spittle ability, they gain Blood Rage.

Blood Rage (Ex) As free action on your next after taking damage in combat, may choose to enter rage gaining +2 Str, +2 Con, and -2 AC for remainder of battle or 1 minute, whichever is shorter. Cannot end rage voluntarily.

Silver

These xenomorphs have reflective, almost mirror-like, metallic carapaces. They gain an additional +2 natural armor bonus and increase their DR by 1/adamantine. They gain the Dazzling Sheen and Reflective Hide special abilities but lose Spittle and suffer a -8 racial penalty on all Stealth checks.

Dazzling Sheen (Ex) When you are in an area of normal or bright light, all sighted creatures within 10 ft. of you are automatically dazzled unless they avert their eyes (granting concealment to you).

Reflective Hide (Ex) When targeted by a ranged touch spell or a laser weapon, attacker must roll d20 + caster level (or character level, if using laser) against DC of your CR + 11 as if you possessed Spell Resistance. If the attacker fails to overcome your resistance, the spell or laser is reflected back at them using their same attack roll to determine a hit, and you are unaffected.

White

The white xenomorphs possess a nearly pure white carapace and lack acid spit and blood. Instead their bodily fluids are extraordinarily frigid and damaging to things exposed. They lose immunity to acid and instead gain immunity to cold. Their Acidic Spray and Spittle abilities replace acid damage with cold damage.

Yellow

These xenomorphs have a dull yellow carapace and appear somewhat larger or more plump than other xenomorphs. They are absolutely filled nearly to bursting with their acidic ichor, and their Acidic Spray ability functions as if they were one size category larger, and they can use Spittle an unlimited number of times per day. They lose the Improved Natural Attack (bite) bonus feat.

SPECIAL ABILITIES

Acidic Spray (Ex) As immediate action, spray blast of acid on any creature damaging you in melee. The spray deals 1d2 acid damage, split evenly between weapon and attacker (if weapon is unarmed strike or natural attack, full damage applies to attacker). A successful DC 11 Reflex save halves the acid damage. The save DC is Constitution-based. If attached to a creature when the facehugger is injured, that creature also takes 1d4 acid damage with no saving throw.

Attach (Ex) When you hit with touch attack, latch onto target and anchor in place. You are considered grappling, but your target is not. You lose your Dex bonus to AC and can be attacked normally or grappled; if target manages to win a grapple check or Escape Artist check against you, you are shaken loose. Gain +8 racial bonus to maintain grapple once you are attached.

Blindsight (Ex) Maneuver and fight as well as sighted creature as long as you have line of effect. Invisibility, darkness, and most kinds of concealment are irrelevant. Do not need Perception check to pinpoint creature within range provided you have line of effect.

Hazardous Corpse (Ex) The squares occupied by your corpse (same size as your Space) are considered difficult terrain. Any creature or unattended object in or moving into the area automatically takes damage equal to your Acidic Spray damage per round. The area remains hazardous for 1 round per HD. This can damage the floor and even cause your corpse to fall through if it is sufficiently damaged.

Impregnate (Ex) Against a helpless opponent of size Small or larger, implant xenomorph embryo in 1d20 minutes. A remove disease spell (DC 20) kills the implanted embryo. A DC 20 Heal check can remove the embryo. If successful, embryo is removed and implanted creature takes 1d4 bleed damage. On a failed check, implanted creature takes 2d6 damage, 1d4 bleed damage, and the embryo is not removed (although additional attempts may be made). After 2d4 hours, the embryo grows into a chestburster that rips its way free, killing the host.

Poison (Ex) contact; save Fort DC 13; frequency 1/round for 6 rounds; effect unconsciousness 1 minute/2d4 hours; cure 1 save. Save DC is Constitution-based.

Spittle (Ex) 3/day—As standard action, spew acid as ranged touch attack with a range of 15 feet (no range increments). A creature struck takes 1d4 points of acid damage.

Strangle (Ex) An opponent grappled by you cannot speak or cast spells with verbal components.

Suffocate (Ex) A creature affected by your strangle ability can't breathe and must hold its breath or suffocate.

The tiny arachnid-like stage of the xenomorph life-cycle lives only to incapacitate and impregnate creatures with an endoparasitoid larva. It is adept at capturing prey. It tries to attach itself to a foe and then both strangle and poison it. If either succeeds in rendering its target unconscious, it will implant a chestburster embryo before detaching and dying.

Chestburster

A flesh-colored snake-like creature has vestigial limbs and razor-sharp teeth.

A successful DC 9 Reflex save halves the acid damage. The save DC is Constitution-based.

Scent (Ex) Can detect opponents within 30 ft. by smell (60 ft. if opponent upwind, 15 ft. downwind). Strong scents (smoke or garbage) at twice range and overpowering scents (skunk or troglodyte) at triple range. Exact location not revealed, only presence within range. As move action, note direction of scent (pinpoints when within 5 ft.). Track by smell with Wisdom (or Survival) check (DC 10 for fresh trail on any surface). Increase DC by 2 per hour of trail's age. Otherwise as Survival skill ignoring surface conditions and poor visibility.

Spittle (Ex) 3/day—As standard action, spew acid as ranged touch attack with a range of 15 feet (no range increments). A creature struck takes 1d4 points of acid damage.

The nymph form of xenomorph, the chestburster seeks to flee and hide so as to grow and mature. It is not suited for combat but quite adept at stealth and evasion. It begins rapid growth and fully matures in 1d12+12 hours. After 1/3 of this time passes, use the adult stat block with the Young template applied twice. After 2/3, use the adult stat block with the Young template applied once.

SPECIAL ABILITIES

Acidic Spray (Ex) As immediate action, spray blast of acid on any creature damaging you in melee. The spray deals 1d6 acid damage, split evenly between weapon and attacker (if weapon is unarmed strike or natural attack, full damage applies to attacker). A successful DC 23 Reflex save halves the acid damage. The save DC is Constitution-based.

Breath Weapon (Su) Can use breath weapon once every 1d4+1 rounds to create a 60-foot cone of green gas. Those caught in the area of the gas can attempt a DC 23 Fortitude save to resist the effects, but those who fail the save are immediately petrified. This petrification is temporary—each round, a petrified creature can attempt a new DC 23 Fortitude save to recover from the petrification as long as it is not caught within the area of effect of your breath weapon a second time while petrified. A creature exposed a second time while already petrified becomes permanently petrified, and can no longer attempt to make additional Fortitude saves to recover naturally. The save DC is Constitution-based.

Combat Reflexes Make a number of additional attacks of opportunity per round equal to your Dexterity bonus. May make attacks of opportunity while flat-footed.

Greater Bull Rush When you bull rush an opponent, his movement provokes attacks of opportunity from all of your allies (but not you).

Improved Bull Rush You do not provoke an attack of opportunity when performing a bull rush combat maneuver.

Spittle (Ex) 3/day—As standard action, spew acid as ranged touch attack with a range of 30 feet (no range increments). A creature struck takes 2d4 points of acid damage.

Trample (Ex) As full-round action, attempt to overrun any creature at least one size category smaller than you without making a check; simply move over opponents in your path. Targets can make an attack of opportunity at -4 penalty or forgo attack to attempt a Reflex save (DC 10 + 1/2 HD + Str modifier) for half damage. Can only deal trample damage to a creature once per round regardless of how many times you move over target.

A successful DC 20 Reflex save halves the acid damage. The save DC is Constitution-based.

Combat Reflexes Make a number of additional attacks of opportunity per round equal to your Dexterity bonus. May make attacks of opportunity while flat-footed.

Extract (Ex) If you begin your turn with all four tentacles attached, a successful grapple check automatically extracts the creature's brain, instantly killing it. Cannot be used on constructs, elementals, oozes, plants, and undead. Not instantly fatal to foes with multiple heads.

Fleet While wearing light or no armor and not carrying a medium or heavy load, base speed increases by 5 ft.

Grab (Ex) If you hit with attack associated with this special attack, deal normal damage and start grapple as free action without provoking an attack of opportunity. Normally, only usable against targets of equal or smaller size. You can either conduct grapple normally or take -20 CMB on future grapple checks on simply use body part to maintain grapple but do not gain grapple condition yourself. A hold does not deal damage unless you have constrict special attack. If you do not, each successful grapple check in successive rounds deals damage for attack initiating the hold. Otherwise, it deals this damage and constrict damage. You receive +4 bonus on CMB to start and maintain a grapple. In addition, if you begin your turn with at least one tentacle attached, you can attempt to attach remaining tentacles with a single grapple check. Opponent can escape with a single successful grapple check or Escape Artist check, but you get a +2 circumstance bonus for every tentacle attached at the beginning of the opponent's turn.

Mind Blast (Sp) Equivalent of a 4th-level spell.

Mobility Gain +4 dodge bonus to AC against attacks of opportunity caused when you move out of or within a threatened area. A condition that makes you lose your Dexterity bonus to AC (if any) also makes you lose dodge bonuses.

Multiattack Secondary attacks with natural weapons take only -2 penalty.

Spittle (Ex) 3/day—As standard action, spew acid as ranged touch attack with a range of 30 feet (no range increments). A creature struck takes 2d4 points of acid damage.

Acidic Spray (Ex) As immediate action, spray blast of acid on any creature damaging you in melee. The spray deals 2d6 acid damage, split evenly between weapon and attacker (if weapon is unarmed strike or natural attack, full damage applies to attacker). A successful DC 30 Reflex save halves the acid damage. The save DC is Constitution-based.

Awesome Blow As standard action, make combat maneuver check against corporeal opponent smaller than yourself. If successful, deal damage (typically slam plus Str modifier) and knock opponent flying 10 ft. in straight line direction of your choice where it then falls prone. If opponent collides with immovable object, opponent and obstacle take 1d6 damage, and opponent falls prone adjacent to object.

Bleeding Critical When you score a critical hit with a slashing or piercing weapon, your opponent takes 2d6 bleed damage each round on his turn, in addition to the damage dealt by the critical hit. Bleed damage can be stopped by a DC 15 Heal check or through any magical healing. The effects of this feat stack. Can only apply one critical feat to a given hit unless you possess Critical Mastery.

Improved Bull Rush You do not provoke an attack of opportunity when performing a bull rush combat maneuver.

Poison (Ex) Sting—injury; save Fort DC 32; frequency 1/round for 6 rounds; effect 1d4 Strength damage; cure 3 consecutive saves. The save DC is Constitution-based.

Power Attack Take -5 penalty on all melee attack rolls and combat maneuver checks to gain +10 bonus on all melee damage rolls. Bonus increased by half (+50%) if attacking with a two-handed weapon or a one handed weapon using two hands. Bonus halved (-50%) if attacking with an off-hand weapon. You must choose to use this feat before making an attack roll, and its effects last until your next turn. Bonus damage does not apply to touch attacks or effects that do not deal hit point damage.

Spittle (Ex) 3/day—As standard action, spew acid as ranged touch attack with a range of 30 feet (no range increments). A creature struck takes 2d4 points of acid damage.

Swallow Whole (Ex) If you begin your turn with an opponent grappled in your mouth, make combat maneuver check. If successful, opponent at least one size category smaller is swallowed dealing listed damage each round. Target keeps grappled condition, but you do not. Swallowed creature can attempt to cut free using light slashing or piercing weapon; if successful, you cannot swallow another creature until damage is healed. If target breaks grapple, it ends up back in your mouth where it can be bitten or swallowed again.
