Action Mastery is a passive progression system that tracks the player's actions in combat. Every Pilot the Player can use tracks its actions separate from all other Pilots.
When a Pilot reach a specific threshold, they unlock a unique ability. Each Pilot has their own Mastery Milestones separate from all other Pilots. The Action Mastery system tracks the following actions for each Pilot: the number of times this Pilot takes a Defend, Sprint, Ballistic Attack, and Laser Attack actions, the number of times this Pilot used an Activated Ability, and the number of times Hail has been activated (just for Bell). Action Mastery Milestones do not exist sequentially; the player can contribute to all Action Mastery Milestones at the same time.
