For the conventional stages, a useful 10-slot starting template:
- 3 meatshields
- 2 affordable attackers to clear small enemies
- 2 stage-specific counters
- 2 main damage dealers
- 1 flexible slot for extra defense, control or a combo
Adjust it for the blind-spot stages (Unlimited Bladeworks, King of Heroes, Delusional Heartbeat), where durable close-range attackers matter more, and for the wave stages (Consumed by Shadow), where keeping the wave blocker alive matters more than adding another expensive attacker.
Awakened Bahamut is an optional rusher here; Crazed Bahamut fills a different, slower ranged role. The plans work without him, but don't substitute one form for the other.
Every stage page has CATS TO BRING: wiki picks where the wiki has a plan, community runs (labelled COMMUNITY) for the rest.
