Hello you N'wahs, I have never done anything like that, so how do I get started? What I want to do is basically just change the default models of items like "Boots of blinding speed" and "Randagulfs Fist" to match the bonemold Armor set. Also, I want to adjust the armor value of the Redoran Guard Helm to match the armor value of the Redoran Master Helm. Any help would be appreciated.
