With the new items and gameplay changes of Diablo III's superb 2.3 patch, one of the coolest builds of old times, the Archon, is back and got stronger for Season 4.
It's a fun build totally worth trying out with the new patch, that focuses on the Wizards's massive Archon ability, something that was neglected for a while now (just like Wizards).
Here's a very well made video guide by YouTuber Fevir, explaining everything related to this build and proving that it's OP as hell by completing a really tough level 60 Greater Rift.
Grabbed from the video above, here are all the items and skills needed (zoom in to see the text). As you can see it's a very item-dependent build, with tons of Life on Hit and Cooldown reduction as well as items like the Vyr's set, a new Season 4 item called Fazula's Improbable Chain and the Chantodo's set. All equipped in order to boost the Wizard's Archon ability.
