Many people doesn't seem to understand this robe on TLP , i am currently playing on agnarr and this item is by far THE BEST DPS item in game for any cloth user.
Not only it provide you 40 mana regen by clicking it versus the 24 mana regen you get while medding. People are talking about the damage that you take but raid or group buffed or even using fungus staff cover the majority of that damage so its negligable!
Moreover , many raid target in velious / luclin / PoP has a ton of HP so going out of mana on those fight is very common. Not to mention that when using a mount med + this clicky stack so raid like (Vex Thal - PoP , etc = cash!!).
I would definately buy another one if i had to do it again , best item ever!
Cheers,
