Tycho Celchu, Rebel Rz-1 a-wing states:
“While you have 2 or fewer stress tokens, you may perform actions, even while stressed.”
The rules reference states: “If the overlapped ship was an enemy ship, if it is not stressed, it may immediately perform a focus or calculate action from its action bar, treating the action as red. Then the ship skips its Perform Action step.”
If Tycho overlaps an enemy ship while stressed, is he able to perform a red focus?
