Changeling Origin

Changeling Origin is an origin for the Origins framework. Once a player has the origin, the player can shapeshift into other creatures. Shifting is tied to kills: a creature killed by the player can become the next form available, and the new form then gives access to that creature's special ability, which is activated on demand. A shapeshift toggle turns the form on or off, and a player who is already shapeshifted returns to their original form by reverting. Death also returns the player to the original form.

The origin is meant for survival and adventure play, and it leaves the choice of which creatures can be copied to the server owner. Entity types, tags and a denylist can stop particular creatures from being used, and by default creatures are allowed, with the Wither, Ender Dragon and Vex left out of the list of copyable forms. Changeling Origin requires Origins, Shappoli and Walkers, and the descendant ability depends on a blood sacrifice being made first. The mod is published for Fabric and Forge for 1.20.1, with 1.0.0+1.20.1 as the latest file, and it is released under the MIT License as open source.
