Aedans Unicorns (Fabric)

A Fabric 1.21.1 mod that gives horses a dedicated Unicorn Horn slot, lets the horn render on their head, and introduces the Potion of Unicorn Vitality line.

Gameplay

• Unicorn Horn: rare loot in bastions, nether fortresses, smith/village chests, desert pyramids, dungeons, end/ancient cities, and woodland mansions. Lives in the Combat tab.
• Horse horn slot: appears under the armor slot. Shift-click a horn to equip; it renders on the horse’s head.
• Totem effect for horses: a slotted horn saves the horse from death (except void), clearing effects and granting Regeneration, Absorption, and Fire Resistance.
• Potion of Unicorn Vitality (Absorption II for 2:00): brew Awkward + Unicorn Horn. Convert to splash (Gunpowder), lingering (Dragon’s Breath or Awkward Lingering + Horn), and tipped arrows (lingering potion + arrows for 8). Custom containers show in Food & Drink; vanilla potion variants are hidden.
• REI integration: supplies custom brewing and arrow recipes while hiding misleading vanilla permutations (optional but supported).
