Item Glow
 

Is it posible to add a glow to an item.. (armor) ? Yes? how No? damn.. ^^

Definitly not with a normal UI-AddOn.

Im not sure but you would have to change certain models and you might have to create some models on your own. And since Blizzard disabled the old way of modelchanging this
1. might get you banned
2. is probably very difficult

So better dont try ;)
