ToME: the Tales of Maj'Eyal

Could we please agree to try avoiding that?

I have no problems with digging into a wall to reach loot, but i just met the Xorn boss in Daikara 5 and he died inside a mountain, so potential artifact and nice loot are lost to me

Question: Are you playing tiles? With graphics, that is. Not in ASCII.

It's a known (though I'm not sure if addressed) bug that tiles mode messes with the mountains in Daikara, turning some of them undiggable. This bug doesn't occur in ASCII.

You might try swapping over to ASCII temporarily to see if it'll let you dig, then.
