Escoffier build

is this a decent escoffier build? im trying to pre farm her and i made this build with extra artifacts + the strongbox so this is low effort. final stats with level 90 weapon and lvl90 escoffier would be 2065 attack, 150% er, 70% cr and 180% cd. i would run her on a furina, yelan, escoffier, skirk team. i kept rolling crit pieces instead of atk and er so idk if i have enough of those stats. im most worried about the er since i struggled getting er sub stats, some guides said the amount i had was good but some people say you need 180%+???
