There's more than that 4zb4. Almost every action will go towards training some stat. Using any hefty weapons and digging will train AStr. Easiest way to train LStr is to carry lots of stuff. Dodging will improve Agi. Dex is the easiest by far; opening doors, setting traps, picking up items and using light weapons come to mind. Per can be raised by dodging as well, and zapping wands. Cha you don't need to worry about, it has little use so far.

A digging level? Only way that'll be anything but a death trap is if you put lots of food on it.

I've a better idea. The stairs up and down are right next to each other. However, there are pockets of empty space throughout the rock that either hold a chest with food and other goodies (high quality) or enemies. The enemies being more common than chests, naturally. Perhaps no more than 2-3 chests scattered here and there that require a lot of digging to reach.

Why thank you, fine sir, but that will not prevent the inevitable

I believe that has, in fact, been done before. Wasn't there a wand of apocalypse or something someone coded?

No no no. Look at my sig.

I do believe I must second Erno. 4zb4++ indeed, that is true

After all this time... It is done.

Petrus is, in fact, not immune to leprosy. Infect away boys, I see a nugget town in future...

I have found out that being teleported into a square with an active trap can set off said trap.

When you expect skeletons to pop out of the ground around masked people.

I've never known that to happen before. Good find.
