Choose one of four classes of mages and start your adventure on the Tower of the Archmage! Customize and create your own spells, defeat your foes in strategic turn-based combat, discover many different enemies, random runes, unique creatures and 25 floors of procedurally-generated dungeons. Be careful, for many dangers await you in the tower, and your death will be permanent, though your successor will always keep some of your knowledge.
