ToME: the Tales of Maj'Eyal

Makes the game more difficult (and makes racial XP modifiers more important) by reducing all gained experience by half:

Completionists should still be at or close to level 50 for the final fight, although it may vary from race to race.

Note: the overpowered GMHWs are guaranteed to spawn, which is a great source of XP (if you're out of your mind ).

Well I wont be using this for a *long* time, mostly because I've never got past daikara or the derth quest.

I just wanted to note that this addon doesn't make the game impossible. This character (a cornac) won the game on Roguelike difficulty. The one death was from being over-ambitious against a guardian on the High Peak. The character was level 50 going into the final fight, and it didn't do every single side-quest:

Next, I may see what it's like to play as a ghoul with this addon. I'm sure I'll need to do a few farportals to stay reasonably leveled.

C'mon, more "expert" players need to try this addon!
