I've been fine tuning a previous PoB I had for league start based on using the reworked Emperor's Vigilance shield. I usually only have time for 1 character per league and in the end will try to min-max it and do end game content with it.

Note: I am not yet in maps with this build, but I've done the RT/impale gladiator version back in 3.15 so I have background with where to take this in endgame.

There is a tree and item set for league start and endgame. The rares are really really basic (no eldritch implicits/influences) and there's so much room to min-max this still. I've never had Ashes and that's my chase item as it gives us over 130+% crit multi.

Also I'm really bad at remembering to use flasks while I play (or automate them), so I didn't even factor those into the DPS or eHP numbers.

tl;dr vs Guardian/Pinnacle boss:
League Start Equip:
5K life | 1K ES
2.3m impale DPS w/o totems | 4m impale DPS /w totems
49K EHP w/o guard | 78K EHP guard
Ailment immunity from tree/crafts

Endgame Equip:
5.5K life | 1K ES
4.8m impale DPS w/o totems | 9m impale DPS /w totems
49K EHP w/o guard | 79K EHP guard
Ailment immunity from tree/jewels
