How do i take off Dern Dagger on Warrior class?

I haven't played wynncraft in years and i decided to have another go at it and I'm playing the ninja class. I saw that i had the dern dagger but it wasn't on my ninja class. I went to all my other classes and saw that it was equipped on my Warrior class. Does anyone know how to can unequip it from the Warrior class and equip it to the ninja class? I've been tempted to delete this class in hopes to get it but I don't want to do anything too permanent before I looked for other options.

 

Cosmetics are shared across all classes; if you have the dagger skin it's tied to your account, not the specific class you're on.

 

You can equip/unequip skins in your compass menu or with /use ingame.
