Reincarnation Origins: Dullahan

The mod is a Fabric add-on that depends on Origins and Pehkui. Once the origin is chosen, a player gains the Dullahan form, which focuses on ranged and magic combat rather than melee. Abilities include summoning a Nightmare Steed on request, shooting explosive wither skulls at targets, impaling a target with a barbed chain that slows it and applies wither, and gaining a terrifying presence that blinds and weakens nearby entities.

Much of the progression is tied to souls and hunger. Standing close to a soul campfire channels souls into the body and satiates hunger, and the Dullahan feeds on souls from victims caught in soul lanterns. Soul lanterns cannot be crafted directly, so souls must be ensnared by killing within a lantern carried in the offhand. The form is stronger at night and weaker during the day, and hunger rises with the souls consumed.

Servers that run it need every player to install it too. It is published for Fabric only, for eight release versions 1.19.2 – 1.20.4, with 1.0.1 for 1.20.4 as the latest file. The code is released under the MIT License, so it is open source.
