Peacekeeping: clear the objective
Read the three-star conditions before entry. Clear mobs efficiently and save your most reliable damage for the boss. A grouping hero such as All Might or Tokoyami is a practical starting choice; Ochaco offers accessible area damage. This selection is editorial advice, not a stage-by-stage tier list. [S29]
Match the problem
If mobs consume the timer, improve grouping and area damage. If the boss survives, improve single-target uptime. If a star requires low incoming damage, stop relying on Auto and dodge deliberately. A successful clear and a three-star clear are different goals.
Supply: farm the bottleneck
Use Supply when food, credits or training materials are actually holding back an upgrade. Favor a fast, consistent clear over a complicated boss build that spends half the stage ramping up. Historic blanket claims that Supply is never worthwhile ignore early progression and server reward changes. [S20, S30]
Hero Trials: choose a shard target
Farm the heroes you intend to raise. Iida suits long manual boss fights, Ochaco offers a simple damage route and Tsuyu is a common AI investment. An SSS+ shard conversion strategy depends on the actual shop rules; do not assume every hero or WHM variant is eligible. [S07, S24, S27]
Practice goal
Pick a farm stage and learn a clean opener, one dodge and a finishing sequence. Once it clears reliably, optimize time. Repeating an unstable attempt for a small theoretical damage gain is usually poor farming.
Evidence limits
The historical Peacekeeping manual documents teams, star objectives and fatigue, but originates from an early regional version. Exact fatigue, stamina, rewards and unlocks should be read from the current client. [S29]
