Dark Shackles
The colorless uncommon skill Dark Shackles costs 0, exhausts, and gives the target 9 stacks (15 upgraded). On application it silently applies that much negative Strength; at the end of the enemy's own turn the power removes itself and restores the Strength. The reduction is in place for the enemy's next attack and gone afterward.

Notes
Strength has no floor, so an enemy at 0 drops to -9 and every hit of a multi-hit attack loses 9; a triple hit loses 27 damage. Play it on the turn the big attack is telegraphed, never earlier, since it does nothing for later turns. Misery can copy it to other enemies without doubling the loss on the original.
Rules and timing
It takes away Strength when gained and gives the same amount back when it is removed, at the end of its owner's turn.
If you haven't bought Slay The Spire 2 yet, it's time. Support the devs, they made an amazing game.
