Team Composition for Crisis Drills
Crisis Drills are pure combat challenges with no unique mechanics, so balanced team composition works best.
| Slot | Role | Recommended | Why |
|---|---|---|---|
| 1 | Main DPS | Physical or Heat operators | High damage output |
| 2 | Sub DPS | Elemental counter to enemy type | Flexible damage |
| 3 | Support | Healer, buffer, or CC | Team sustain/utility |
| 4 | Tank | High DEF/HP operator | Damage absorption |
Pro Tip: F2P Team
Endministrator (free 6-star starter) can serve as strong DPS for early Crisis Drills. Build around: Endministrator + available 4-star Physical operator + basic Healer/Support + basic Tank.
Clearing Strategies by Region
Origin Lodespring (Early Game, Authority 20-25)
Use Level 15-20 operators, basic team composition, prioritize DPS over sustain. Good practice run to gauge combat readiness.
Power Plateau (Early-Mid, Authority 25-30)
Consider enemy element weaknesses, bring elemental counters if known. Slightly stronger team than Collection Site.
Jingyu Valley (Mid-Late, Authority 30-35)
Clear Management Room first as warm-up. Institute may have higher enemy HP or more waves - bring stronger DPS.
Wuling City (Endgame, Authority 35+)
Wait until Authority Level 35+. Use E2-E3 promoted team. Best operators available. Prepare for challenge.
Maximizing Crisis Drill Value
First Clear Priority
- • Complete all accessible sites when discovered
- • Don't delay - Oroberyl valuable for pulls
- • Emergency Sanity Boosters help daily farming
- • All 6 sites give identical first clear rewards
Replay Assessment
- • Check if replay worth Sanity after first clear
- • Compare to Protocol Space efficiency
- • Some sites may offer repeatable Oroberyl
- • XP gains via enemy kills
Common Mistakes & How to Avoid Them
1. Trying Containment Vault too early
Problem: Attempting Wuling City site at Level 20-25. Fix: Progress naturally. Clear earlier sites first to build team strength.
2. Ignoring Emergency Sanity Boosters
Problem: Not using ESB for daily farming. Fix: Use ESB proactively for high-Sanity days (weekends).
3. Skipping weaker sites
Problem: IGNORING Origin Lodespring/Power Plateau. Fix: All 6 sites give identical 50 Oroberyl reward. Clear them ALL!
4. Not using Oroberyl from rewards
Problem: Saving Oroberyl when you need unlocks NOW. Fix: First clear Oroberyl is free income - use it to accelerate progression.
