Slots and levels are separate
A companion’s level is not a move’s level. Unlocking a fourth move slot is also different from adding a fourth card to each upgrade selection.
Review the build while paused
Pause to inspect your loadout, stats and damage by move. The move pool includes the companion’s own kit, its evolution line and shared moves from same-type League members.
Some items raise caps further. Check TM Case and Max Ether for their effects on moves, fusions or vitamins before planning around them.
