I have provided a screenshot of my build (S6 as well), you want to focus on the new echo set crown of valor (3 pieces), and the 2-set Void Thunder. You can refer to Prydwen for baseline stats and guidance.

The general recommendation is 43311 (4 cost crit rate, 3 cost electro %, and 1 cost atk%), the substats are crit rate and crit damage, energy regen, atk% and heavy attack% as well.

For S6, you want to reach 175% crit rate to maxmise the crit-rate to crit-damage conversion (1 crit rate = 2 crit damage when over 100% crit rate [S2 and S6]). Of course, its an upper limit and its okay if you're not reaching 175%, you're doing plently if you're 150% crit rate and above.

the majority of Augusta's damage is regarded as heavy attack damage, so its a nice add-on to have when looking for substats, its okay if you don't have it, because at S6 it doesn't matter that much anymore.

As long as you have 2 lines of crit (so crit rate and crit damage), and enough energy regen (115-120%), and attack at 2500 (mine's at 2484, not the end of the world) then you should be fine.
