Monks GI armor
 

You know, like armor of Wu, that gives you that specific "straps GI" look

I was under impression that when beastlords were first made, this type of armor was also made available to them. I could swear I saw troll and barbarian BST with human monk GI texture (in old models) back on LIVE around time of Luclin

I have experimented with this, and I can't reproduce this.
I know its texture type 4, and it does shows up correctly on human monk, but on anyone else (including BSTs) it shows up like a regular leather armor.

any ideas?

Only Human, Iksar and Drakkin have those armor models available. To all other races, they look like normal leather. I think you could have any class use this texture as long as they are one of those 3 races. But since most other classes can be other races, I am pretty sure there isn't an option for it normally on any class other than Monk, including Beastlord.

well yeah I have tried all possible combination:
Human BST
Barbarian BST
Barbarian Monk

So I can see how its limited to a race (just like dwarves don't have robes), but its also limited by a class. Even for NPC - npc human monk would show up in GI armor, but any other human npc, including monk GMs will not.

Too bad... I wanted to make some Human BST in Wu's ;)
