Train heroes, equip your squad and win automatic battles against enemy bosses.
Battles run automatically. Tap an enemy to focus your squad. After five basic attacks, tap a charged skill to cast early; otherwise it casts automatically after the eighth basic attack. Collect drops, grow heroes, and adjust your squad before the next boss.
Later stages increase enemy numbers, variety and strength. Upgrade the squad and equip collected items before retrying a difficult boss; entering a new chapter does not automatically grant heroes or equipment.
Unlocked stages, heroes, progress, and preferences are saved only in this browser. No account, purchase, online profile, or cloud save is required; clearing site data can remove the local campaign.
