Step 20 of Act 3 in "Beat a Rising Chorus" demands precise coordination to overcome escalating enemy waves. Success hinges on strategic ability rotations and positioning. Follow this exact sequence:
Optimal Party Formation
- Frontline: Place two shield-bearers at NW and NE positions to absorb frontal assaults
- Mid-Row: Position a healer directly behind the frontline for AoE recovery coverage
- Backline: Deploy ranged DPS units facing South to prioritize caster-type enemies
Critical Phase Execution
At the 00:45 timestamp, enemy reinforcements spawn in three waves. Execute this counter-sequence:
- Wave 1 (00:45): Activate frontline taunt + healer's regeneration field simultaneously
- Wave 2 (01:10): Trigger DPS ultimate abilities immediately after blue enemy cast bars appear
- Wave 3 (01:30): Rotate shield-bearers' invincibility skills with 2-second staggered timing
Resource Management Rules
- Cooldown Cycling: Never use all healing items within 15 seconds – maintain minimum 3 emergency kits
- MP Conservation: Keep at least 40% MP reserves for final wave burst requirements
- Environmental Use: Lure melee enemies into the central lightning zone at 02:00 for 200% damage bonus
Failure occurs most frequently during phase transitions – immediately pause ability casts during golden enemy transformation animations (1.8 second window) to reset aggro tables. Post-completion, inspect your battle log for healing-per-second values; optimal clears maintain HPS between 1200-1500 throughout.
