You call forth spirits of the dead, which flit around you for the spell’s duration. The spirits are intangible and invulnerable.
Until the spell ends, any attack you make deals 1d8 extra damage when you hit a creature within 10 feet of you. This damage is radiant, necrotic, or cold (your choice when you cast the spell). Any creature that takes this damage can’t regain hit points until the start of your next turn.
In addition, any creature of your choice that you can see that starts its turn within 10 feet of you has its speed reduced by 10 feet until the start of your next turn.
At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for every two slot levels above 3rd.
When you cast this spell, you present the gem used as the material component and choose any number of creatures within range that can see you. Each target must succeed on a Wisdom saving throw or be charmed by you until the spell ends, or until you or your companions do anything harmful to it. While charmed in this way, a creature can do nothing but use its movement to approach you in a safe manner. While an affected creature is within 5 feel of you, it cannot move, but simply stares greedily at the gem you present.
At the end of each of its turns, an affected target can make a Wisdom saving throw. If it succeeds, this effect ends for that target.
