Acid (Ex)

A trapper’s acid does not harm wood or stone.

Smother (Ex)

A trapper can try to wrap a creature up to one size smaller than itself in its body as a standard action. The trapper attempts a grapple that does not provoke an attack of opportunity. If it wins the grapple check, it establishes a hold and deals slam and acid damage each round the hold is maintained. Further, a grappled opponent must hold its breath or suffocate. Attacks that hit an engulfing trapper deal half their damage to the monster and half to the trapped victim.


Characters with ranks in Knowledge (dungeoneering) can learn more about a trapper. When a character makes a successful skill check, the following lore is revealed, including the information from lower DCs.
