Unless you play an alchemist who can make stuff for 1/3 of the price. Not game breaking, but I wanted other people's opinions. My guy's the alchemist.
I get to add my int mod to splash weapons and bombs, including splash damage. so that alchemist fire I just threw? if splash plays against each square a creature occupies? He takes 1d6+4 initial and 5 extra per square if we change it like Tanis says.
Or if splash damage just applies once to a large or bigger creature? 1d6+9 (+4 int, +1 splash, +4 int added to splash). not that bad at level 4 is it? especially when I can throw 2 with TWF at 4th, 3 at 5th (rapid shot and TWF) and deal 3d6+30 (assuming my intelligence goes up by 2 at that point and splash damage applies only once per large creature.) fire resistance 5? oops, you only took 3d6+25. Oh wait, I threw acid? or Liquid Ice? oops, no resistance.
I take issue with the fireball comparison. Fireball doesn't deal splash damage at all. Not the same thing.
