The contracts walkthrough routes human players from zero pacts to S-tier devil agreements without wasting yen on wrong floors or captains. Contracts define ability bars, synergy with clans, and raid roles — consult contract tier list before committing weeks of grind to Fish Devil.
Phase 1: Floor Zero Farming
After beginner steps, descend Floor Zero. Weak devils drop introductory materials and occasionally unlock early contracts like Fish or Frog — usable placeholders only.
Phase 2: Division Captain Contracts
Captains from divisions walkthrough offer story-locked pacts. Division 3 path documented in Division 3 guide gates specific devils.
Phase 3: Target A-Tier Then S-Tier
- Fox Devil for yen and mission speed
- Bat or Snake for build synergy — Gun Hunter wants Snake
- Octopus or Ghost for raid readiness
- Curse or Mantis for min-max clears
