the 101 HK aura is obviously the best one to use as it adds the most patt/p crit damage, as said anything that boost those even if it's just a little helps as many small tweaks can add up to quite a difference.
2 simple obvious examples would be:
- use bless epics, either real or shadow versions as bless valakas adds alot to patt/STR and crit damage increase of lindvior earring is quite noticable when stacked with the aura
- use STR dyes for patt and skill effects, STR/CHA dyes for even more boost - it's small but again it all adds up
AP set up for PVE should be very obvious?
4x HP / 4x Patt / 2x Acuracy for rampage shield passive / 2x both crit options / 2x elemental patt <= all of these are in the Warrior branch
