Buffart=ReplaceableTextures\CommandButtons\BTNBarkskin.blp
Targetart=Abilities\Spells\NightElf\Barkskin\BarkSkinTarget.mdl
Targetattach=chest

anyone ???

i think it added armor to the target...

All I can tell is that it was a buff of some type, and probably a unit target one. It doesn't exist in the abilitydata.slk so your outta luck if you wanted to re enable it that way.
