Basically the title a passive regen would be nice, I absolutely spam devour with canniblize rune and even have reaping as a passive and still the essence can’t keep up with my bone spirit spam, trying to do a 105, I literally had to kill myself 3-4 times just so I could refill my essence this is a horrible design flaw. I have 308 essence, I know it can go to about double that but it still doesn’t seem like it would be enough, Devour just can’t keep up even if I’m one shotting mobs.
Bone Spikes, Grim Scythe, Siphon Blood all generate essence.
It’s not a design flaw that players choose to make builds that don’t take them.
Are you reffering to the masquerade bone spear build? You said bone spirit and bone spirit doesn’t cost any essence, so I am assuming you meant spear. You get the reservoir rune on the Simulacrums no matter what so your essence is always doubled.
Are you also playing seasonal? If yes then by cubing Railena’s Shadowhook as the 4th slot you transform half of your max essence as a dmg multiplier. This is important, as you want to have essence on your weapon and off-hand and pick the passive that grants you 40 more essence. Your max essence can be 660 (without stone of jordan) and that means you get a 330% more damage or 4.3 x multiplier if you prefer.
If you chose to skip a generator with this build, this makes it faster and more suitable for speed content but you will hit a wall eventually. You have to figure out how high your ceiling is. The deciding factor here is if you can drop the boss without completely emptying your essence. The stronger you are, with better items, paragon, augments, higher gems, the higher you can clear without having to rely on generators. I speed GR115s right now and the only tricky thing for me is the rift guardian. I have to time my bone spears with my COE cicle otherwise the essence will not be enough to kill it. Appart from that i rarely even see my essence drop below 70-80%. If you can’t rely on your coprse consumption and dark reaping, then you cannot avoid a generator. Grim scythe seems to be the most preferable one.
If it helps here is my build,

As i said i clear easily 115 within 4 minutes and maybe even 3 mins when the map is good. The 3rd and 4th item are RoRG and Shadowhook but they will not show on the d3 planner. You can say it is a bit unorthodox because i sacrifice a lot for speed and laziness but it seems to be working fine up to GR115-120. And i don’t have to worry about anything. Not even krysbin procs, cause zei’s stone + frostburn seems to be always proccing it. I am not saying it is better than the usual variations you see in guides but it is so fast, it is ridiculous. Of course i have pretty decent items and 2k paragons, but i don’t remember having a problem in GR105 earlier this season. Rift guardian takes one rotation (4 seconds) to usually die. And worst case senario if it spawns and my cold just ended i only have to wait 8 seconds before i start throwing bone spears. At GR120 i can still play with the same setup. Full clear takes around 5-6 minutes and the boss requires 2 rotations of COE to die. Above lvl 120 i would need to replace something with grim scythe.
