Spell: Blood Oath
Charges from the healing you generate, then waits. A blow that would kill you is cancelled instead: you are left at 1 HP, briefly untouchable, a shockwave throws enemies back and the enemy behind that blow dies on the spot — yielding nothing. The rescue has a price: for 10s all healing is dead, your shield shatters and nothing can rebuild it. Every use in a run doubles what the next one costs. In new runs, the rescue also clears all existing Corruption Echo debt.
