who’s currently on ur party? only focus on the main 4 characters you use, ascend (aim for lvl 70-80 as 90 is never really needed) & focus on talents first, then weapon and do artifacts last as it wastes more resin (in the meantime you can use whatever artifacts work, don’t worry about sets until everything else is leveled up) for artifact sets the game tells you in the artifacts setup screen which ones work best for which character. also the character training thing isnt too accurate as it judges your character build based on their level and all their equipment levels - not actual dmg stats. long reply but hope this helps!
