Because kobolds rely on traps to soften up enemies, kobold alchemists learn to turn bombs into traps. When such alchemists are preparing defenses against larger creatures that might enter their tunnels and attempt to exterminate them, their skills mean the difference between life and death.
At 2nd level, an alchemical trapper can use one of her bombs to make a trap. Setting a bomb trap is a full-round action that provokes attacks of opportunity. A bomb trap fills a single 5-foot square and cannot be placed in the same area as any other trap. The alchemical trapper needs the same materials required for making a bomb. The DCs for Perception checks to notice the trap, Disable Device checks to disable it, and saving throws to avoid it are equal to the DC for the alchemical trapper’s bombs. All bomb traps have location triggers and do not reset. The alchemical trapper can use any one discovery that applies to a bomb when making a bomb trap. The bomb trap lasts 10 minutes for each alchemist level the trapper possesses. If the bomb trap is not disabled or exploded within that time frame, the trap becomes inert.
Creating a bomb trap uses one of the alchemical trapper’s bombs per day.
This ability replaces the discovery at 2nd level.
At 4th level, an alchemical trapper can find and disable traps, as the rogue class feature of the same name.
This ability replaces the discovery at 4th level.
