What a commander does

Once a week you decide who goes and who rests. The mercenaries handle the rest.

They fight, you decide

  • Battles play out on their own. You set the party, the rows and the gear.
  • Every battle ends within three minutes, and you can speed it up.
  • The party screen shows this floor's dangers and what your party does not answer yet.

Official community

Notices, updates, store news and the commander's guide in one place.
