After i got the skyshard from bahraha's gloom i took a look at the sets hews bane has to offer and sadly much like spawn of maphala are also underwhelming, so me being me i typed some retrains to actually make them more usable mainly because both their stats and effects are mediocre at best, Have a look for yourselves.
