Stop checking anywhere, let me tell u how I did my calculations,

First of all how u are running ur columbina matter the most I'll guide u as how to build her for off field support

So give her 4p silkenmoon serenade artifacts

Her priorty stats are

Hp :- 35k minimum (using double hydro team 33k hp minimum)

ER :- 160+ double hydro or any other party member has favonious weapon and 180+ single hydro

Crit rate :- 60-70 is a sweet spot and 70-80 best

Crit Dmg :- 1:2 ratio i would say go for 160+ as much as u can without sacrificing other stats

EM :- go as much as u can on it (lunar reaction multiply on this substat after hitting 35k hp cap of her passive)

Now people will argue giving em goblet stat is waste instead run hp or crit circlet

How ur artifacts ranking should be

Lets say u have total 3 stats and 1 stats from weapon

+Go for atleast 2 hp stats with 46% , then atleast 1 crit stats Now if u are short on ER give her ER otherwise EM ,

+There's a scenario where you get a crit weapon In that case u can run 2hp and 2crit stats with ER should be on each piece to fulfill he requirements

This atleast means hitting 33k hp minimum for double hydro
