Re: Luck: Fountains can only train so much per dungeon level, same with any other stat training. The full list
found here, for a bit longer is
Luck
* Adventuring at a dungeon depth higher than your character level trains luck -- it's dangerous and involves great risk-taking!
* Using an item with a random effect (such as a wand of wonder) and getting a beneficial effect trains Luck. [Note from frumple: I don't think there are any random effect items in the game >_>. Well, except that hat, maybe...
* Using a magical fountain and gaining a beneficial effect trains Luck.
* Surviving a critical hit from an enemy trains Luck.
And ah, re: Stability. Yeah, about the only way to get stuff back without an alignment hit is bartering or requesting them back which... I think requires a minimum of 13 cha, at least for the former. You can also usually summon stuff on top of them if you've got complicity turned off >_>
As for loot hiding... iirc, the work-around to that was to drop your bags on the ground before taking the character dump.
Aannndd re: Ashy, yeah, I don't remember if he was bugged or not... think he was at one point, but I want to say he wasn't in the latest version (Which, iirc, was actually 6.9
H4. If you check the change log, .9H2 and .9I are identical. I'm... about to go check, actually.). Would have to kick on an ashy priest to check, I guess, but... lazy. Dude was always a bit of a pain to gain favor with, despite being arguably one of the best gods for casters (due to that inherent potential... a human ashy wizard can get
ridiculous spell DCs, hohoho... ashy/sabine would be even better, but sabine's even
more annoying to worship, to a degree.).
E: Yup. H4 is newer than I. Boss M never did fix that for us poor windows buggers...
