The Horn of Fear can be hardened all the way to [[Green Light Crystal]] and the Horn of Bravery to [[Diamond]]. While as of yet horns are among the [[Invincible Items]] in all versions of IVAN (variants included), you might want to harden or SoCM the Horn of Bravery to a lighter material. The original Horn of Bravery in its original form weighs in at a whopping 4200 g - more than nearly all weapons and some armor!
