  • Mischievous Naberius - Level 38 Party Members (Sharla, Dunban, Riki) - this takes advantage of the damage bug when fought on high ground. Furthermore, this prevents Naberius from using ground attacks such as Titan Stamp.
  • Mischievous Naberius - Level 44 Party Members (Dunban, Riki, Shulk) - Consecutive Chain Attacks and Blossom Dance. Ideally, this will prevent Naberius from making a single attack.
