Trick Weapon

As a Bonus Action, you can switch between the Transformed and Untransformed states of this weapon. In its Untransformed state, the Dream Executioner is a Scythe and a lantern. In its Transformed state, the weapon is a single massive Maul.

Untransformed

The Scythe gains the Harvest property.

Harvest

Whenever a creature of CR 1 or higher (or level 1 or higher) dies within 15 feet of you, the lantern harvests the creature's soul. The soul becomes trapped in the lantern, and the creature can't be resurrected until the soul is freed. As a Magic action, you can free a soul trapped in the lantern. The lantern can hold a maximum of one soul.

Transformed

The Maul gains the Soul Explosion property.

Soul Explosion

When you hit a creature with this weapon while a soul is held in the lantern, you can sacrifice the soul, permanently destroying it, to create a massive explosion of ghostflame. Each creature of your choice in a 15-foot Emanation originating from you must make a DC 14 Dexterity saving throw, taking 2d8 Radiant damage and 2d8 Necrotic damage on a failed save or half as much damage on a successful one. Undead automatically fail the saving throw.
