Explosive Bomb (Discovery)
Ability Type: Su
Benefit: The alchemist's bombs now affect an area of 5x5 squares centered on the target (or the designated square of the target's space, if the target is sized-large or larger), rather than 3x3. This only increases the splash damage radius; the primary target damage is not affected.
Note: This is a 'bomb modifier' discovery, and may not be combined with any other 'bomb modifier' discoveries, until the alchemist learns the Eureka Bombs class feature at level 17.
