dont forget that at 300ish, Xmute Mooncloth is still yellow and will give you a skill up
Also, when you hit 350 skill you can Xmute all 3, Primal Mooncloth, Spellcloth and shadow cloth to yeild you another 3 skill ups.
the 4 day cool downs on the Xmutes dont help much if your powerlevleing, and the 350 Cloth Xmutes still take a Bolt of Imbued netherweave +priamls...but, its something.
