So with the new patch out n everything, the lightweave embroidery wich u can get as a tailorer(now has a chance on spell cast to give 250SP).
It procs of Fel armor to warlocks when it heal u, this means that if u keep beeing below 100% health it got a chance to proc giving u more SP for 12sec or so i think it was...
Usefull dps boost :P
(ps sorry for my bad english it is not my mother tongue, if u find something hard to understand just ask and ill try to explain better)
