Also, the burning scrolls are far too forgiving. Books seem to burn immediately (like always) while the scrolls just catch fire and give you plenty of time to read and use them. If anything it should be the other way around, since a book would obviously take far longer to burn than a sheet of parchment.
I think there's an old post around here that does the math, but dual-wielding is pretty much always a better idea than using a shield, since you can block attacks with weapons anyways.
1. wait for golem to approach
2. attack
3. move out of the way (golems that can't see you will move in the direction they were attacked from)
4. abuse 's' until the golem is next to you again*
5. repeat
* this reminds me that 's'earching is far too quick; it should take as long as waiting with '.', or at least swap the times of s/. since searching taking less time than "waiting" is just weird.
If you kick it enough they'll eventually spawn a hostile angel, so be careful...
Chaotic books would be the safest way down, or go and offer everything to that chaotic alter you have. Otherwise you could try using chaotic weapons, but those don't affect your alignment too heavily.
Consider bones on the minefield level: you can end up with two minefield floors.
Obviously it would be a bit weird to encounter two shops, since there are unique NPCs involved.
For the chest, the reasoning was likely that the items in the chest are usually very powerful (AoLS, cloning/mirroring, etc.) and allowing the player to get two (or more given enough bones files) could have been considered unbalanced.
