My first ever Paizo forum post! Yay!
Anyway, I'm reading the playtest rulebook and I think there's a repated copied-and-pasted error in several alchemist feats.
Smoke Bomb has it right: it says it is a reaction triggered when you make an alchemical bomb. Several others seem to have the same incorrect text pasted in repeatedly: Debilitating Bomb and Sticky Bomb both say they are triggered by creating an elixir rather than a bomb. The exploitative Bomb goes back to being triggered by the creation of an alchemical bomb. :)
The wording seems to have been copied and pasted from the triggering condition for Combine Elixirs.
Anyway, another couple of things for the inevitable errata. :D
