A different maze every day
The date decides the layout, the element and the boss, so everyone on the server runs the same dungeon and can compare notes. Tomorrow there is a different one.
UDub Dungeon
A new dungeon every day. The same one for everybody, gone by midnight.
Built from real rooms
Every room is a schematic somebody built by hand. The generator only decides how they connect.
One a day, or a friend's
Your daily buys your run. Clearing one earns a shard, and a shard buys you into somebody else’s.
Loot that stays down there
Dungeon gear does far more damage to dungeon monsters than to anything else, and no more than usual on the surface.
