Companion Training
How companions level up and what training unlocks.
A companion trains by fighting: every wave survived with it equipped adds experience. Training levels raise a DPS bonus that stacks account-wide across all trained companions.
How it works
- Only the equipped companion gains waves.
- Each level needs more waves than the last.
- The DPS bonus of every companion adds up globally.
- High training milestones unlock the companion’s ability tiers.
Rotate companions — an idle farm run is a cheap way to push a fresh companion toward its ability tiers.
