Osimu Boss Fights

This mod adds very unforgiving bosses and cool rewards. Most of them will be glass cannons, strength alone won't be enough.

This mod was originally made for a private server, but I figured why not publish it. Osimu Boss Fights is a mod that adds very hard and unfair bosses, usually glass cannons but something gimmicky bosses too. It takes from a wide range of other references and media, they won't be lore accurate, just made for fun. Current bosses:

  • Frieren
  • Độ Mixi

Strength alone won't be enough.
