Mo-Variants

Variants appear in the existing mob spawns of the world, grouped into several categories, so players meet altered versions of familiar creatures during ordinary exploration. Certain custom mobs carry a helmet that grants night vision, and an Undead Barbarian leaves a battle item found nowhere else. The author notes that a few extra axes are included and that more custom items may be split out into separate packs in later updates.

Server owners install the mod on the server, and players only need the server side to see the variants; the server must run it, while a client may leave it out and still join. A large Skeleton Barbarian boss is included as a single encounter. The mod contains optional integrations with other packs, including Time Lib Integration for versions 1.20.3 and above, which can enable or disable seasonal variants automatically. Integrations are optional and exist only to adjust the experience. Seasonal variants can be turned off through a config toggle, and a command can customize the experience further.
