Alchemical effects

Alchemy bundles up a monster’s abilities and sticks them into a bottle. When you use an alchemical substance, you’re using a monster’s ability.

Drink a potion to gain a dire spider’s wall climbing ability.

Throw a bomb to poison a foe with the spider’s venom.

Distill the spider’s webbing into a glue-like oil that bonds together whatever it touches.

Who does alchemy affect?

Potions only affect creatures with living processes. If you have blood, if you breathe, if you eat food, potions affect you. Creatures like the undead and automatons can neither benefit from nor be harmed by potions.

Bombs are usually chemically reactive with the air around them, creating fires, acid, webs, vines, etc. These substances affect both creatures and the environment, unless the GM makes a call otherwise.

Oils are chemical compounds that can make what they touch sticky, slippery, hot, invisible, etc. These substances affect whatever they touch, be it living or unliving, unless the GM makes a call otherwise.
