Ephemeral Chains

You summon spectral chains that bind the life force of creatures within range. Choose up to three creatures you can see within range. The targets must succeed on a Constitution saving throw or become restrained by the ethereal chains.

While restrained by the chains, the targets experience visions of their own mortality and feel the chilling touch of death. At the start of each of the restrained targets' turns, they take 2d8 necrotic damage, and you regain hit points equal to half the total damage dealt to all targets.

If a target succeeds on its saving throw or the effect ends for it, the target is immune to this spell for the next 24 hours.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, you can target one additional creature for each slot level above 5th.
