ERTAZI's vengfull spirit

Invoking ERTAZI, you cause a vengeful spirit to erupt from yourself. Each creature in a 15-foot Emanation originating from you makes a Strength saving throw. On a failed save, a target takes 2d6 Necrotic damage. On a successful save, a target takes half as much damage only.

then you may make 1 melee weapon attack against a creature that failed the saving throw teleporting to within 5 feet to do so then if the creature hits zero hit points from that weapon attack you may attack another creature teleporting to within 5 feet of that creature this is chainable 3 times.
