"You can run..." Fear+Movespeed Alternate Setup: https://www.youtube.com/watch?v=itHHe8VSzp4
This build began as an attempt to turn SpeedSplosion into a higher GR build. Then the thought occurred to me, partly as a joke and partly not - "What if instead of focusing on buffing Corpse Explosion damage, I focused on buffing all of the passive damage?" The build applies the same concept as what I refer to as "passive murdering potential" in the SpeedSplosion build but ratcheted up a notch and increasing survivability at the same time. I'm consistently getting clears of 2:30 in GR60 and 3:30 in GR70 which puts it right on par with SpeedSplosion at GR60 and better at higher GRs (because it's quite a bit tankier).
Blind Faith, Frostburn, and Bone Spirit: Possession are all applying different types of CC to enemies to maintain the full Krysbin's damage buff. With SpeedSplosion we're running around with just the first tier Krysbin's buff, which is plenty for GR60 but can hurt as you go higher. Blind Faith is really handy here - it and Frostburn are going off simply by the bone storm hitting enemies and Bone Spirit is used on Elites. The 10-second charm is kindof insane honestly. Put that on an elite and it's over. Put a charge on each champion in a 3-pack and it's over. It doesn't work on RGs (or Juggernauts of course) unfortunately, but the blind and freeze do work on RGs. Blind Faith has a 20% variance range on the chance to blind (20-40%) so this can really make a difference - you want it as high as you can get it obviously.
I really recommend going with Wisdom of Kalan as this provides both more DR and more movespeed. That said, I've done it with a Hellfire (with Overwhelming Essence on it) and it was okay - there aren't a whole lot of great options for a fifth passive currently though because Fueled by Death is currently bugged and doesn't scale properly. You could also use Spreading Malediction but it's really not necessary and we can't make very good use of it anyway because the build kills trash really quickly. Overwhelming Desire could be an interesting choice as well, but unfortunately I don't have a good one to test with currently.
You can use Dizzying Curse in place of Opportunist on Decrepify but I prefer the movespeed.
The rune on Blood Rush is totally optional - Potency, Metabolism, and Hemostasis are all good options. I usually use Potency just because I designed this to be a bit tankier for higher GRs but Metabolism is probably a better choice for GR60.
Aura of Frailty is really useful for slapping a curse on enemies to give us the Trag's Fang damage buff simply by walking by them (which we have to do anyway with this build).
Devour: Cannibalize is being numlocked! There are many videos on how to do this, so I'm not going to go into a lot of detail there, but here's a good tutorial by Quin69: https://www.youtube.com/watch?v=JaAI8s8rft4 I'm actually not using a force move key here though, I'm just holding/tapping left-click to move. You can use this to kindof control when you absorb corpses - so long as you're holding left-click, Devour won't go off, but if you tap it it will. Any time you stop to cast Decrepify it's going to activate as well. This synergizes extremely well with Bone Spirit because every time you devour a corpse it reduce's Bone Spirit's cooldown - so much so that I find I'm actually saving it more than I need to in most cases, and I'm still trying to break that habit. It is primarily intended to be used on elites, but the cooldown gets cut down so much that you're not really hurting yourself by keeping it on 2 charges + cooldown at all times.
How does it work?
So what exactly is happening with this build? Basically, all of our damage is being applied passively via our bone storm (thus the "lazy" moniker). You walk up to an enemy with your bone storm on, it hits them which does its own damage and it applies Toxin, and when it crits it applies Pain Enhancer (this is why CHC is so important here). Blind Faith and Frostburn are being proced by the bone storm hitting. The various sources of CC are ensuring that we're getting the most out of our passive damage by maintaining the full Krysbin's buff. Between all our damage buffs and the storm+Toxin+Pain Enhancer enemies just melt. Everything else here is designed to give us more move speed, more toughness, or crowd control for more damage.
How to play:
1) Numlock Devour as soon as the rift begins
2) Use Decrepify on enemies
3) Start up your bone storm on the enemies and use it when it's off cooldown
4) Stand next to enemies for a second or two then keep moving
5) Use Bone Spirit on elites and occasionally throw it on larger trash (if you feel like it) to keep it at 2 charges+cooldown at all times - it recharges extremely fast from Devour
Teleport forward if there are gaps between groups of enemies or you hit a dead end, otherwise just run by/through enemies.
Bonus Fear+Movespeed Alternate Setup (good for GR60 content):
-Drop Blind Faith and equip full Inarius
-Swap Dayntee's for Krelm's Buff Belt
-Swap RoRG for Rechel's Ring of Larceny in the cube
-Swap Frostburn for Warzechian Armguards or Stewart's Graves in the cube
-Change Bone Spirit: Possession to Bone Spirit: Panic Attack
-Change Blood Rush: Potency for Blood Rush: Metabolism
-Swap Decrepify: Opportunist for Simulacrum: Reservoir (this can be pretty much anything but Simulacrum: Reservoir is literally "press this button and do more damage" so it's simple; you could also do something like Ice Golem)
Cast Bone Spirit at least every four seconds (Fear also counts for the triple Krysbin's buff, by the way), keep moving forward, watch stuff die behind you. I have a video of this setup in the description.
