So, in beginning to play a sunder-oriented character, I was struck by a few things about Sundering that aren't 100% clear in the rules:
Can you sunder an alchemist's bomb. It would see that you would, as the rules state that the alchemist is using a 1oz vial with alchemical liquid in it, in the same fashion as a spell component. I assume that if an alchemist were to throw a bomb while in my threatened area, I could sunder as an AOO and potentially destroy it. However I've heard the argument now that it is a supernatural ability, i.e. the whole process is a supernatural ability and thus doesnt have hardness or HP and can't be sundered.
That brings me to the second question, is this a way to essentially stop spellcasting in my threatened area with successful sunders? For example, an opponent takes out a twig as a part of a spell, they attack, provoking, and I sunder the spell component (not pouch since they've already taken it out), and the spell can't be continued without it. The same is true of potions and oils. I guess my question specifically is what triggers the attack, beginning to cast the spell, or ending it? All of these questions are somewhat moot, if your opponent quaffs the potion and finishing the potion is what provokes, not starting it, if I were to sunder an empty potion vial, it makes no difference, and I wouldnt even be able to sunder a bomb if they'd already thrown it at me.
