Lose 6 health. Apply Spell Weakness: 1

Lose 6 health. Apply Spell Weakness: 1
Combat · Skill
Use Unholy Pact before a spell sequence that can justify its health loss. Keep the 1-energy cost and Exhaust in that calculation, since applying Spell Weakness alone does not recover the health paid for setup.
Exhausted cards can only be played once per combat or explore.
