[Arnabas]

Just a quick question. I finished the SP module and am working on a module of my own. During the SP, I noticed that certain creatures don't seem to have the abilities I am used to them having. For example, it used to be that to kill a troll, one needed fire or acid. Now it seems that anything can kill them. They do seem to regenerate (very slowly), but when they are dead, they stay dead. I remember hacking trolls to tiny little pieces, which then pulled together to regrow. What happened? Is this a 3rd ed change, or is it specific to NWN?
Also-- why don't dragons use their breath weapons in this game? tehy seem to possess them, but during my whole run through the game, no dragon ever used it. What a waste. It's like my character saying "hey I have a +5 sword, but I'll just use my non-magical dagger instead..."
