ToME: the Tales of Maj'Eyal

What's the difference between Normal and Nightmare in Arena? It seems to me that enemies are at the similar level. And I got only normal achievement (Level 10).

Everything works fine

No. I haven't found the Spellblaze lore. Never. And I don't have the appropriate .achievement

I just saw that all lore from shady library in Elvala disappeared. It is still there if I start a new character....

I have 12 % Fatigue without anything. The only unusual thing I have done was adding and removing generic skills points many times.

My character:

I got to the 21st level of Infinite Dungeon and I haven't got achievements Infinite x10 nor Infinite x20
