I've spent over 2000 gold in preparations trying to beat The Indomitable . . . 50 extra lives? Sheesh!
Anyways, each time I tried, I hit some kind of glitch that crashed the game. Finally, one of them caused me to be teleported to the bottom left square of the dungeon. Something I can report on!
The things I did that may lead up to the bug:
Tons of gaining MP and removing Magic resistance
Tons of PISORF into walls/monsters
One giant Mana Leak
The action that triggered the bug was the Refreshment boon.
