Starfinder: Infiltration Arachnid

Remember those soldiers who supposedly died on the battlefield? Well, they are still dead, but their weapons and armor are now being used to infiltrate the ranks!

Originally designed to be used in construction and repair, this heavy-duty welder was commonly used by many companies, and was considered to be the state of the art arc welder.  And of course some creative individual decided it would make an excellent weapon!

The device requires two hands to hold. The power cells are contained in the handle of the device, and it has two long prong-like ‘barrels’ which normally could open and close in order to spot-weld, but have been changed so that they will instead fire the electrical charge.

The weapon has a very short range, and will not be effective past the listed range. After it strikes a target, the electrical discharge will then arc to a second target within 10 feet, albeit for less damage, but it is still effective. This arc will randomly strike any target, be it friend or foe. However, it will always arc towards anything carrying or wearing metal. The more the metal, the more likely the arc will strike them. When a critical strike is achieved, the arc will continue onto a third target (if available), for less damage still. Furthermore, if a successful critical hits, the target will suffer additional damage from electrical burns.

Chameleon Exoskeleton (Ex): As a swift action, the creature can change its exoskeleton to match the background. This includes other arachnids that might be around it!

When it uses this ability, its claw attacks are at +14 to hit, and do 1d10+12 damage each and a critical strike knocks the target prone. The creature can do this once every three rounds.

Special Abilities

Hardened Survivor (Ex): The evolved tank arachnid is completely immune to poisons and radiation, and it is able to withstand extreme conditions, even utter vacuum. Whenever the beast must make a saving Fortitude saving throw when dealing with environmental conditions, it gains a +10.

Stream of Fire (Ex): The creature, as a full round action, can spray a stream of napalm-like chemical fire. The stream is 10 feet wide and can reach out to a maximum of 150 feet. Anyone caught in the stream area of effect is allowed a Ref save (DC 23) or take 8d12+18 flame damage. A successful save cuts the damage in half.  To make matters worse, the flame will continue to burn for 1d3+1 rounds, unless the victim is able to somehow smother the flames (rolling in dirt, dousing in chemical fire-extinguishing foam, jumping into a river or large body of water). Also the napalm-like fire will remain on whatever terrain it coated when the arachnid used this ability and will last for 1d3+1 rounds before burning out. The Evolved Tank is able to use this ability once every second round.

Swallow whole (Ex): The creature is able to potentially swallow whole any creature it bites which is at least one category size smaller. See page 156-157 of the Alien Archive for more information.

Trample (Ex): As a full-round action, the creature can move up to twice its speed and literally run over any opponents at least one size category smaller than itself. The Evolved Tank merely has to move over the opponents in its path. The creature does not need to make an attack roll; each creature whose space it moves through takes damage. A target of a trample can make a REF save (DC 23) for half damage. If it attempts the save, it can’t make an attack of opportunity against the trampling Tank due to the creature’s movement. The Evolved Tank can deal trample damage to a given target only once per round.

Burst Fire

This is an optional rule which allows the shooter to fire a single ‘burst’ of rounds. The average burst is usually 3 rounds or charges (depending on the usage of the weapon in question) per pull of the trigger. Firing a burst incurs a penalty of -2 to hit, but the damage of the attack is increased by 25% (round down). This consumes the equivalent of 3 full shots (rounds or charges, so that if the weapon would use 4 rounds or charges for a single shot, using it on burst fire will now consume 12 charges). The burst will affect only a single target.

Special Abilities

Hardened Survivor (Ex): The Infiltration arachnid is completely immune to poisons and radiation, and it is able to withstand extreme conditions, even utter vacuum. Whenever the beast must make a saving Fortitude saving throw when dealing with environmental conditions, it gains a +10.

Mimic (Ex): The Infiltration arachnid has the ability to somewhat mimic a humanoid it has encountered. By ingesting part of the victim, the Infiltration arachnid is able to take on a few basic traits of the victim. It can morph its head to appear like that of the victim, and it can speak – or rather parrot – simple phrases in the victim’s own voice. As such the Infiltration arachnid gains a +10 to disguise and +5 to bluff when dealing with others, as long as its body is covered by powered armor. It is a full round action to consume flesh of the victim, and then 1d4 rounds for the creature to absorb the DNA so it can mimic it. The Infiltration arachnid can only use the genetic material of a single individual at one time, and it can retain the face of that victim indefinitely, although it can choose to revert to its regular features at any time. This is a full round action for the creature to do so.

Strength limitation bypass (Ex): Normally powered armor has a strength limitation, which states that even if the wearer is stronger than the strength provided by the armor, it is limited to the armors strength. This creature is able to bypass this and use its own natural strength instead.

Weapon and Armor proficiency (Ex): The arachnid has the uncanny ability to use any type of armor or weapon it encounters, and as such it does not need to have the appropriate proficiency in order to do so.
