So I currently have 1100 artifacts in stash and I somehow feel most of them are trash. At least my champs are way weaker than from what I see other peoples stats with their champs are. Even tho I'm using hell hades for optimization.

My current rules are:

Sell all 4* and all common/uncommon gear

https://19216811.cam/

Sell all rare gear with 1 flat substat (HP, def, art)

https://1921681001.id/

Sell all epic gear with 2 flat substats

Sell all gear with 2 or more rolls on flat substats

sell hands, chest, feet with flat stats

on legendary gear I don't have rules yet because I don't have many anyway (mostly farming Dragon 20 atm)
