The gem that spawns Jewel Guardians, for a Pit Push personal best, I found that replacing that gem and taking the hit to stats and losing unhindered is so worth it, and replace that gem.
Because, in my 100 attempt the Jewel Guardian took aggro from my Hydra and the boss took twice as long to kill. It was awful.
Realistically using the cheat death gem in its place worked for me because, I was able to clear 100 last night. You can get unhindered with Flame Shield / break crowd control. Teleport helps as well.
Yes you lose a boat load of stats, and the cheat death isn’t that great… (It was the only viable gem available to me).
And yeah I was able to clear The Pit 100 with Hydra Sorcerer in Season Nine.
