(None) You become a ghostly visage and possess one creature you can see within range, impairing their ability to move or make decisions. The target must succeed on a Wisdom saving throw or become restrained. At the end of each of its turns, it takes 1d12 psychic damage, and it can then make another Wisdom saving throw. On a success, the spell ends on the target.
A restrained creature’s speed becomes 0, and it can’t benefit from any bonus to its speed.
Attack rolls against the creature have advantage, and the creature’s attack rolls have disadvantage.
The creature has disadvantage on Dexterity saving throws.
You invoke both death and life upon a 10-foot-radius sphere centered on a point within range. Each creature of your choice in that area must make a Constitution saving throw, taking 2d6 necrotic damage on a failed save, or half as much damage on a successful one. Nonmagical vegetation in that area withers.
In addition, one creature of your choice in that area can spend and roll one of its unspent Hit Dice and regain a number of hit points equal to the roll plus your spellcasting ability modifier.
You magically distract the triggering creature and turn its momentary uncertainty into encouragement for another creature. The triggering creature must reroll the d20 and use the lower roll.
You can then choose a different creature you can see within range (you can choose yourself). The chosen creature has advantage on the next attack roll, ability check, or saving throw it makes within 1 minute. A creature can be empowered by only one use of this spell at a time.
