Fully solo play. I've cheesed it in the past with 5-ways, back when those were a thing. I also have quite a few lvl 98 and 99s from prior seasons, but I usually can't find the motivation for the last push. 8 days, 8 hours playtime, although there is some afk time counted there.

My build is an adaptation of Taaki's autobomber. He designed it for Occultist, but I adapted the build for Elementalist. It's a true autobomber unless you feel like using movement skills. Grafts do 100% of the damage. [https://www.youtube.com/watch?v=6KICiSLpzLQ&t=7s](https://www.youtube.com/watch?v=6KICiSLpzLQ&t=7s)

The playstyle is the same what you see in Taaki's video. Note my more expensive items - Mageblood and 3p voices - are not mandatory. 

Levels 98-100 were a mixture of strats: harbinger, alva, and delve. Harbinger seems more dangerous and less lucrative than alva. Delve is dangerous, not very lucrative at this point in the league, and low xp, but I love it so who cares. I made 120 divs between 99-100 from temples, simulacrums, scarabs, and whatever the Kingsmarch mappers looted. For any shabby players like myself still looking to hit 100, I strongly recommend this strat: [https://www.youtube.com/watch?v=1QPl9NWITDg&t=347s](https://www.youtube.com/watch?v=1QPl9NWITDg&t=347s) \- lots of gold, lots of xp, and a fair amount of ground loot considering how rough it is this league.

First real lvl 100
