Pathfinder 2e Action / Feat: Mega Bomb

Requirements Expanded Splash; You are holding an infused alchemical bomb you crafted, with a level at least 3 lower than your advanced alchemy level.

Description You add an incredibly powerful additive to a held bomb to create a mega bomb, greatly increasing its area and power.
Applications You use an Interact action to throw the mega bomb, rather than Strike, and you don’t make an attack roll. The mega bomb affects creatures in a 30-foot-radius burst, centered within 60 feet of you. The bomb deals damage as if each creature were the primary target, with a basic Reflex save.   On a failed save, a creature also takes any extra effects that affect a primary target (such as flat-footed from bottled lightning). While all targets in the area take splash damage as primary targets, there is no further splash beyond that area. If your next action after creating a mega bomb isn’t an Interact action to throw it, the mega bomb denatures and loses all effects.
