Is the build viable in current season with Echoing Fury in hand and cubing Sacred Harvester?
Totally. Very nice build. It used to be the top wd some 4-5 seasons ago. With ring of emptiness and echoing fury buffs it got stronger, albeit somewhat behind now to the more powerful zunimasa and the new mundunugu. It can probably fight for the second place with a slight buff in the figure. Still one of my favs. You can also cube wormwood to make a lazier version of it.
Cool. Trying it out next since my Wiz is stuck behind dps and Paragon wall.
