Any chance i can make Blood Mage Reaper work on non league

Considering that spec enabling Heart of the Well is seasonal only?

I am lvl 90 , 6200 hp , 0 ress , but only regen i have is Life Remnants.

I literally cant get hit otherwise i am dead instantly.

I really like Reaper theme and i love using Reaping staff.

I am currently sitting at 840 k dps Reap

Bone Cage 690 k

And 72 Chaos res

I've invested 280 Divines into my build and i would really like to be able to make it work.
