Defoliant Bomb

This is a Discovery — a class feature gained through that class's own talent choices, not a feat you pick through normal feat selection.

When the alchemist creates a bomb, he can choose to have it deal extra damage against plant creatures but less damage against other creatures. Against creatures with the plant type, a defoliant bomb deals 1d8 points of damage, plus 1d8 points of damage for every odd-numbered level the alchemist possesses, instead of 1d6. Against all other creatures, the defoliant bomb only deals 1d4 points of damage, plus 1d4 points of damage for every odd-numbered level, instead of 1d6. This is a poison effect. A defoliant bomb kills all normal vegetation in the target's square and its splash area; any plant-based difficult terrain in the affected area becomes normal terrain.
