Here's how I did it with a p860 WD:
-Base build is the same as "God mode 0CD~"
-CDR gem in helm
-Change weapon to SuWong Diviner
-Gems: Bane of the trapped, Zei's Stone of Vengeance (to do more damage while running away from mobs), boon of the hoarder
-Cube: same as build, but change ring to avarice band (to be able to pick up progression orbs without running all the way to them)
-Change Hex - Angry chicken to Horrify - Stalker for the movement speed (since angry chicken is useless without manajuma's)
-Hellfire amulet: confidence ritual
-Passives: Grave injustice, pierce the veil, spirit vessel, fierce loyalty
Rotation: Basically just spam all spells, spamming wall of death more than the others when you need that extra bit of damage
Had to fish for a good rift for like 30 mins, then I had no problem finishing it in time
If it wasn't obvious, I didn't use a bot for this challenge btw.
