SSC Xu Addon

The addon adds several feral forms the player can take on: a fox that purifies with the unstable holy apple, a bat that uses blood gems, a cat that uses emerald essence, an allay that uses space gems, an ocelot that uses wind gems, an axolotl that uses water gems and a spider that uses undead essence. Each form is tied to its own item and changes how the player moves and fights.

Magic is handled through a mana pool with levels. A player whose mana falls to zero enters an exhaustion mode that disables magical skills until mana recovers to 20 percent. Spells include Fire Arrow, which deals heavy damage to a single target for a medium mana cost, and Fire Ring, which knocks back nearby entities. Blood Thorn and Blood Step draw on a blood resource, and Blood Step grants invisibility so nearby enemies lose aggro.

The addon depends on a curse mod for its forms and curse system, so that dependency must be installed alongside it. It is client and server, so the server and every player need it. The addon is released under the MIT License and is open source, with source code and an issue tracker published. Files exist for Fabric on 1.20.1 only, with 1.6.2 as the latest file, dated 2026-08-06.
