Demolition Bomb (Su)
Replaces: Bomb
At 1st level, an alchemical sapper can create a demolition bomb. This bomb deals double his normal bomb damage, half of which is bludgeoning and piercing damage, the other half of which is fire damage. This bomb ignores a number of points of hardness up to 1/2 the alchemical sapper’s level (minimum 1). This counts as an ability that modifies the alchemical sapper’s bomb, so it doesn’t stack with other discoveries that modify bombs. The alchemical sapper can’t use his demolition bomb with the fast bombs discovery. An alchemical sapper can only expend one use of his bomb class feature to create a demolition bomb once per day. He can create one additional demolition bomb per day at 5th level and every 4 alchemist levels thereafter.
This ability modifies bomb.
