The same as the pumpkins with poisonous flasks. 5.

For pumpkins and flasks, if I understand correctly, AP is spent, but they themselves are "inexhaustible". But what's the deal with bombs? AP isn't spent, but what about the "stock"? Are they also in "unlimited quantity"? Or am I getting everything wrong and pumpkins, flasks, and bombs are consumables?
