The Unicorn Horn is found in the Wizard Castle Interior level. You must kill the Painter (the first Boss fight) while his Unicorn painting is alive. It is tied with the Black Morning Star for highest Magic Modifier of any weapon in the game.
The required Level to wield this weapon is Level 15. This is one of the game's many joke weapons.
It has the same buffs as the Black Morning Star, aside from the Morning Star giving a crit chance and requires level 20.
- In Castle Crashers Remastered, this is the only weapon that gives +6 Magic.
