Hotfix
Hotfix (0 Energy, Common, Defect, Exhaust until upgraded) applies 2 stacks of this temporary buff. Gaining it adds 2 real Focus on the spot, so every orb you own is worth 2 more for the rest of the turn, including its end-of-turn passive. When your turn ends the power removes itself and subtracts the same 2 Focus. Playing it twice stacks to 4.

Notes
It uses the same mechanism as Focused Strike's buff but keeps its own counter, so both can be active and each reverts only its own amount. The Focus counts for Evokes made this turn, so Hotfix before a big Evoke is the standard line. Unupgraded it Exhausts, one use per fight; the upgrade removes Exhaust, which is the entire reason to upgrade it.
Rules and timing
It gives Focus when gained and takes the same amount back when it is removed, at the end of its owner's turn.
