Progression & exploration
Campaign
Fight through successive zones, develop your heroes, and return on tougher difficulties for more experience and rewards.

Progress through zones
- Each zone contains seven stages, ending with a boss encounter. Winning a stage opens the next one.
- Clearing a zone unlocks the next zone on Normal and the next difficulty for the zone you completed. You do not need a perfect star score to move forward.
- Zones have three difficulties: Normal, Heroic, and Insane. Higher difficulties can add waves and stronger enemies.
Entries and rewards
- A standard battle costs 3 Stamina on Normal, 4 on Heroic, or 5 on Insane. Instant battles, when available, cost one extra Stamina.
- Victories grant experience and loot. Experience grows with the zone, stage, and difficulty; boss stages provide an additional experience bonus.
- Gold and other drops vary by stage and difficulty. Check the stage preview for the gear and resources you want to farm.
Earn three stars
Win without losing a hero to earn three stars. One hero lost gives two stars; two or more lost gives one star. Replaying a stage can improve its recorded star rating.
Earn all 21 stars across a zone’s seven stages to claim its completion reward for that difficulty. These rewards include summoning scrolls, gear, and Gold. Each zone and difficulty has its own completion claim.
Build for the next encounter
Check enemy abilities before spending Stamina. If a stage defeats your team, improve equipment or change your lineup before trying again. Keeping the whole party alive matters when pursuing completion rewards.
