If you're looking for this, give your love to Horn Scarabas at El Dicastes Dungeon level 1. You need to do a quest to enter the dungeon.

There are some people that would love to get a highly upgraded (think of +9 or +10) dagger like this and spam stuff like Storm Gusts, Magnum Exorcismus and other magic based attacks.

Yeah, it's a pity that Soul Linkers can't use this...
