1. How high can you usefully take your AC? I would expect it to stop helping you around 90 according to the formulae on Bones' site, but for reasons alluded to in my next question I have become convinced that those either aren't the whole story, or work differently for party members. I ask because, just entering Eofel (and so getting close to the end of the game), all my characters' ACs are over 100 with the Monk pushing 200, and I'm wondering if there's any point in half the stuff they've got adding to it.

2. The formulae on Bones' site seem to suggest that, at the very least, you will always have at least a (10 + to-hit bonus)% chance to hit any given critter independantly of its AC. But against Ancient Behemoths (at least), said Monk misses a lot more than the 10% or so of the time I would expect based on this. Discuss.

3. Any ideas on how Luck works? TEF's site suggests it's basically resistance to the same things that the Protection from Magic spell helps you against, but that's the closest thing to solid information on it that I've been able to find anywhere.

4. Related to 3, what, if anything, helps you against instant-death attacks like that of Blood Titans. I realize Grandmaster-level Protection from Magic would protect me from those, but my party has no Cleric so that isn't an option. It's kind of neat having an enemy I still have to flee from even at a point where I'm no longer afraid of dragons, but I'm getting tired of raising my Archer from the dead every five minutes. And you can imagine how my Archer feels about it.

5. A funny thing happened on the way to the forum the Maze. I opened the chest with Haldar's remains in it (questionable quest for a light path group to do, but I decided to be a bit more thorough this time around than I have been in the past) and, since my inventory was getting a bit full, had to screw around a bit to fit some of the other stuff in that chest, and I accidentally closed the chest not actually having taken the remains out. Sloppy on both counts, I know, but normally this is no big deal, you just open the chest again and there's whatever was there previously. Well, not this time. I opened the chest again and a trap went off as though it was a completely new chest, and inside was completely different stuff than before. Completely different really crappy stuff, I might add; it could have been one of the chests in Harmondale near the beginning of the game. Has this happened to anyone else and more importantly, is there anything that can be done about it short of using a savegame editor to add the remains to someone's backpack?
