Thanks for the lists and I’d like to add a few suggestions of my own -
Blackthorne’s Battlegear:
2 Piece:
Nephelam Glory globes have a chance to drop when you hit enemies and increase your damage vs elites by 10% per Nephelam Glory stack.
3 Piece:
While under the effects of Nephelam Glory, you become immune to Desecrator, Molten, and Plagued monster affix ground effects and gain 50% movement speed.
4 Piece:
Increase your damage done and reduce all damage taken by 20% for each Nephelam Glory stack.
5 Piece:
While under the effects of Nephelam Glory, increase all your non-ability, item based damage by 25,000%.
