Ok, so updated PoB: https://pastebin.com/VfTiBStc
There is a starter tree and endgame tree, as well as a starter gearset and endgame gearset.
For both Starter/Endgame I've replaced Flame Golem with Chaos for Phys reduction, added Enduring Cry, and a CWDT-IC-ID setup for mitigation. We also have the Fire Mastery for regen 2% life on igniting non-ignite enemies, which should help with clear. Increased life from tree on both. Max Block Chance.
For Starter we are sitting roughly 1.5M (1.8M w/ Ash) on Sirus. eHP is now 66k Phys, 55K Ele, 9K Chaos.
For Endgame 9.3M (10.9M w/ Ash) on Sirus. eHP is now 62k Phys, 60K Ele, 36K Chaos.
Any suggestions?
