It’s really lazy and stupid fast, i am farming GR100s in 3 minutes and my gear is far from optimized. Frailty and Devour are set to Aura rune so i don’t ever need to worry about pressing them. Bone armor (Harvest of anguish) provides additional movement speed. For both my bone spear and bone armor i am using the cold rune. Phylactery, as i mentioned earlier, is Lost Time. I am using 5 pieces instead of 6, Steaurt’s Greaves, and i have cubed Frostburns in the armor slot. It’s the typical setup you can find in most guides but i ve changed some things.

This season i am using the new set (masquerade bone spears). Even just the steaurt greaves is usually fast enough for most cases. And of course you might want to focus on defence too if you think you are getting killed really often, so i would skip the 3rd and go with the first two. You don’t need to use all 3, that’s kind of an overkill. Usually i am picking the aura rune and i just walk over the corpses that are left behind. I usually pick the rune with the dual charges. For me, i am usually using 2 of these 3 movement speed layers:
