Olivia Method (Faster)

Any / Olivia & Lycanroc (Midnight Form) / Any

  • All three players should have Olivia & Lycanroc (Midnight Form).
  • Remaining Sync Pairs should have a 100% Accuracy move as a safety net in case Lycanroc faints (In battle, be sure to queue moves before Stone Edge from allies).
  • Gear Suggestions:
    • Pin: Equipping a Level 9 or higher 2★ Rock Pin will allow Lycanroc to survive a critical-hit Energy Ball from the enemy Serperior (this has a ~1/24 chance of happening).
    • Bracelet: Equip preferably a Rock-type bracelet to defeat the right side Roserade.

Party Configuration:

  • Center: Olivia & Lycanroc (Midnight Form)
  • Left: Any
  • Right: Any
