Jade still needs more damage. Since it deals damage in bursts, it should oneshot even tougher enemies with ease. Even with Soul Shards giving extra boost, those DoT detonations don’t feel like nukes as they should. I can do GR100 in roughly 5 min but it should be faster at that tier.
Maybe Quetzalcoatl should be adjusted to deal DoT in quarter durarion. Also the Creeping Death passive duration needs increasing from 120k seconds to 240k or more.
