Explosive Bomb

On a direct hit, an alchemist's explosive bomb inflicts 1d6 points of fire damage + additional damage equal to the alchemist's Intelligence modifier. The damage of an alchemist's bomb increases by 1d6 points at every odd-numbered alchemist level (this bonus damage is not multiplied on a critical hit or by using feats such as Vital Strike). Splash damage from an alchemist bomb is always equal to the bomb's minimum damage (so if the bomb would deal 2d6+4 points of force damage on a direct hit, its splash damage would be 6 points of force damage). Those caught in the splash damage can attempt a Reflex save for half damage. The DC of this save is equal to 10 + 1/2 the alchemist's level + the alchemist's Intelligence modifier. Creatures that take a direct hit from an explosive bomb catch fire, taking 1d6 fire damage each turn. At the end of each turn they attempt a Reflex saving throw to extinguish the flames.
