Red Crystal Island is a MonMon Masters dungeon. S-tier MonMon here: Bucktater, Bearsage, Gemgrizzly, Brawlder, Mikorei, Voltafly.

MonMon Lab notes

  • The boss burns your fastest MonMon and grows stronger with every burn on your team, so removing and blocking debuffs is the key.
  • In the team I recommend (Millcastle · Scaraoh · Crestucan · Blizzowl · Castelle), Crestucan's active can't be replaced: both its debuff removal and its +2-turn buff extension pull their weight. Blizzowl's debuff block and revive come next.
  • Funny enough, the same team wins Blue Crystal Island with Scaraoh's Buff Block, which does little here.

Required Tamer level by stage

The tamer level at which we expect the team below to win about half its fights. “≤10” means Tamer 10 is already enough.
