Special Abilities

Alchemical Splashes (Ex) Alchembulks are filled with constantly churning volatile chemicals and active ingredients, allowing them to spew endless streams of noxious substances. Alchembulks can squirt a splash of burning, corrosive, shocking, or freezing substance as an attack action, or up to four with a full attack action. They can also freely mix slam attacks and alchemical splashes during the full attack action. Each alchemical splash has range of 60 feet with no increment and deals 3d6 points of acid, cold, electricity, or fire damage on a successful touch attack and 3 points of splash damage within 10 feet of the point struck.

Critical Reaction (Ex) Any alchembulk reduced to 0 hit points falls apart and then, after 1d4 rounds, explodes in a spectacular 60-ft. radius explosion inflicting 3d6 acid, 3d6 cold, 3d6 electricity, and 3d6 points of fire damage. A successful Reflex saving throw (DC 19) halves the damage. The saving throw DC is Dexterity-based. The explosion doesn't occur if the alchembulk is disintegrated or the alchemical reaction is otherwise suppressed from occurring (be creative).

Enhanced Protection 3 (Ex) Alchembulks have +3 deflection bonus to AC and +3 resistance bonus to their saving throws.

Sense Vulnerability (Ex) Alchembulks have an innate sense of immunities, resistances, and vulnerabilities of creatures and objects within 60 feet, using the most efficient alchemical splashes against those who would harass them and interfere with their actions.

Vulnerability To Impact Alchembulk suffer +50% of damage from falls and sonic damage. They also suffers 1d6 points of damage whenever they are knocked prone or fall from 5 feet.

Alchembulks might form when a catastrophic incident destroys an alchemical lab, the bigger the event, the larger amount of alchemical tools are broken, and the more components are mixed together, the greater are the chances of one or more forming out of the fused remains.

While rarely directly hostile, alchembulks are dangerous nevertheless, due to volatile nature of the fluids and gases they leak, and their irresistible push to consume more and more alchemical components, and break more and more glassware, seemingly trying to recreate circumstances of their own formation.
