Sul' thraze the lasher enchant problem!

the weapon cant handle a enchant and why not? i just farmed it cause i spend 40k on primal mastery and this weapon would look epic with it.

plzz blizz its a classic weapon its not gonna break the game, i swear

Sul’thraze has an existing visual effect. You can enchant it with whatever you want and get the buff, but the visual effect will not override the one the sword already has.
