This is a ranged variant of the Helltooth Gargantuan build that uses Zei's Stone of Vengeance. I have been using it to farm the 90-100 zone, where Bane of the Stricken has not been necessary.
Since all of your damage comes from the pets and the Helltooth set bonus is very easy to keep active from a distance (WoD doesn't need to hit a target), this build allows you to stay out of the pile while your pets eat everything. It also allows you to hide out of range and out of sight of Rift Guardians and avoid annoying mechanics completely.
Another small bonus is that while running through trash to find packs, your pets will have the full Zei's bonus whilst dragging along behind you, helping them to finish off trash as you move.
The core playstyle is more-or-less the same as the ordinary close-range variant, except after grouping the mobs, you'll retreat as far as possible. Having distance also enables you to remain stationary more easily than the close-range variant, allowing for better stacking of the damage portion of the Endless Walk set.
See the Zei's range guide below - your pets should be around the edge of the screen. If your pets move offscreen, follow until they're onscreen again to avoid despawning.
When approaching a pack, it is usually best to keep running beyond it so that your pets respawn nearby instead of fighting distant trash. Resummon them after grouping with Piranhado if necessary.
