Combat Strategy

2Phase 2/3
Core Rotation
4 steps
  1. ▸Start freezing enemies using weapons like the Clock Lancet or Mini Ghost to kick off the Crystal Cries synergy loop.
  2. ▸Collect the hearts that drop from frozen enemies to trigger early healing before the snowball takes off.
  3. ▸Crystal Cries accelerates your Growth, causing rapid level-ups that trigger Hail from the Future.
  4. ▸Hail from the Future drops Floor Turkeys, providing the 8+ overheal needed to trigger Sonia's massive cooldown reduction bonus.
3Phase 3/3
Advanced Play
3 steps
  1. ▸Orologios dropped from leveling up freeze everything on screen, feeding back into your Recovery and Growth loops.
  2. ▸Once cooldown reduction pushes past 100%, the Laurel becomes permanently active and you are completely unkillable.
  3. ▸After the engine is running (around 5-6 minutes), freestyle your weapon choices for kill power since the survivability loop is self-sustaining.
