Yea eacht red crystal increases your XP earned by 0.1x. In version 5.9, I think, It always respawned one of the liches once the dungeon was reset. I just defeated the lich, got out the dungeon, went back in and repeat.
nice way to get XP boosts.
You use the crystal dungeon for XP? my strat is grinding the lich for xp multipliers. for some reason he respawns each time.
Can't figure it out either...
