This mod removes the bags, skulls, and sword from the hindquarters of the armored unicorn mounts. As this is a model edit, it affects all of these mounts, not just one specific color.

Never was a fan of that stuff. : /
As with my other mods, feel free to use this as a basis for your own work. Texture edits, further model edits, etc.
