On page 10 of the rulebook, in A MATTER OF FOCUS, we read "A card’s controller may focus a card to perform an ability or take some other action. When doing so, a focus token is placed on the card".
And then, on page 24 we find "All card abilities fall into one of the following types: constant effects, actions, traits, interrupts, reactions, and keywords."
So, if i'm correct, activate an Action = perform an ability
Now, my question is:
When I activate an Action or any other Ability on a card have I to place a Focus Token on that card to exhaust it?
Example: Repair Dorid [Action: Remove 1 damage from a target Vehicle unit. (Limit once per turn.)]
If I wanna play this Action (during the Action Window) have I to place a Focus token on Repair Droid to remove 1 damage from the target?
This happen with obiectives too? THX
