The horde mode can be completed if everyone is At least 606 preferably 608. It was already done with 2 608’s and a 601. Get your thunderlord for red bars, just to clear the space around the yellow, shotgun for yellow bar scions. Shotgun the machete yellow bar together. When the yellow bar legionaries come out, usually in groups of two, nuke them with a high damage super. Blade barrage, chaos reach etc. cycle orbs. Most importantly stay mobile. Staying in one spot will generally get you killed. If you’re going to camp when the boss spawns you should atleast have one well of radiance.
