Aura of Chaos. Any creature hostile to the Devil of Willowglade that starts its turn within 20 feet of the Devil of Willowclade must made a DC 21 Wisdom saving throw, unless the Devil of Willowglade is incapacitated. On a failed save, the creature sees the Devil of Willowglade as an ally and attacks other creatures hostile to the Devil. At the beginning of the affected creature's turn, they may make the saving throw again at the expense of half their movement. If a creature's saving throw is successful, the creature is immune to the aura for the next 24 hours.

Legendary Resistance (3/Day). If the Devil of Willowglade fails a saving throw, it can choose to succeed instead.

Any humanoid killed by an attack made with this weapon has its soul funneled into the River Styx, where it’s reborn instantly as a lemure devil.

Gauntlet of Flaming Fury.  While you wear both of these steel gauntlets, any non-magical weapon you grasp with either gauntlet is treated as a magic weapon.
