Leech Field

8th-level necromancy

Casting Time: 1 action

Range: 120 feet

Components: V, S

Duration: Concentration, up to 1 minute

You create a 10-foot-radius sphere of violet vapor centered on a point you choose within range. The vapor spreads around corners, and its area is lightly obscured. It lasts for the duration. You can use a bonus action to move the cloud up to 30 feet, although it must remain within range of you or the spell ends. When the cloud appears, each creature within it must make a Constitution saving throw. A creature takes 8d6 necrotic damage on a failed save, or half as much damage on a successful one. Any creature that enters the cloud for the first time on its turn or starts its turn there must also make this saving throw.

The vapor absorbs any hit points creatures lose to it. As a bonus action, you can distribute any number of hit points the vapor has absorbed evenly among creatures of your choice within 30 feet of you, including yourself. Constructs can’t regain hit points from this spell. When you give hit points to a creature this way, the target regains hit points up to its maximum. Any excess is lost.
