Allurite

Aura of Tranquility. The Allurite has a 10-foot aura centered on themselves while they remain conscious. When a creature attempts to move through the aura, they must make a DC 16 Wisdom saving throw. On a failure, their speed drops to 0 for the remainder of this turn, and they are unable to enter the aura for the remainder of this turn. On a success, they are immune to the effect of the aura until the Allurite uses their Ward action. If a creature attempts to attack the Allurite from outside of the aura, the must roll against an AC of 18: the armor class of the aura.
