The alchemist take from 1st level abilities to poison, but at lower level poisons are difficult to buy and expensive. Using this ability is a dilemma :)
So, i was wondering, would you let a player that run an alchemist to take or research some offensive "specific target" spells, that he can use as a poison? For example hold person, that he can put on a weapon and on a succesful hit that deal at least 1 damage the target saves as it was targeted by the original spell. Maybe this could function also on ingestion... it would be nice for a zone of truth (but that works only on target) to play as a truth serum.
