Soul Steal

At-will, std, ranged, costs 2 soul shards; you capture the target's soul (Cha negates). A creature at half HP or below, or helpless, saves at disadvantage. The stolen soul is drawn into a receptacle you carry (a gem, a bottle, a knot of shadow); the body collapses, alive but soulless — comatose, and dying within days without care.

While you hold the soul, you may interrogate it (it can speak from its receptacle), spend it as shards equal to its worth ((5 + Cha) x level for a typical mortal — destroying it), or return it to its body, which is worth a considerable Price in a Contract. Destroying the receptacle frees the soul back to its body.
