Special Abilities

Hardened Survivor (Ex): The warrior 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 50 feet. Anyone caught in the stream area of effect is allowed a Ref save (DC 14) or take 3d6+7 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 arachnid is able to use this ability once every third round.


Calling them Arachnids is a bit of a misnomer. They do not really look like a spider at all; it is just a name which was given to them by those unlucky few who first encountered them. The name was coined to describe the entire species, of which there are dozens of variants.

This particular variant is more like a portable flame-thrower, although the napalm-like flame it produces is nowhere near as deadly as those produced by the Tank Arachnids. It is used in conjunction with the Warriors, liberally spread out through a swarm to hassle and deter the enemy. The drawback is that these fire-support arachnids can only be deployed where oxygen is present, as the chemical needs oxygen in order to combust.

The average Spewer is approximately 8 feet in diameter, and weighs in excess of 300 pounds. They are slightly smaller than the warriors, and are not quite as durable. They move on four legs, possess a large, oval body. A good third of the body is dedicated to the creature’s mouth; although it rarely ever uses it to bite – it would much rather use its stream of fire ability.

When engaging in combat, the Spewers will always stay behind the Warriors, using their stream of flame ability to hamper and hinder any enemy targets. They will even use this ability to create ‘walls’ of flame in an attempt to box in the enemy, allowing the Warriors to close in and kill.

Like nearly all Arachnids, the Spewers are not intelligent, and act strictly on instinct, but show surprising cunning when it comes to combat and working in co-ordination with the Warriors. Unlike the Warriors, when confronted with powerful enemies or those possessing the ability to strike at long ranges, these Arachnids will in fact retreat or at least attempt to find cover.

Finally it should be noted these creatures are immune to the fire they produce – although most other Arachnids are not.

I would like to give a special shout-out to Lloyd Calvin for helping me with this work! Thanks bud!
