I have flins, lauma, C1arle, skirk, Clorinde, alhaitam. Who is better for my account Ineffa or coolumbina?

Ineffa then columbina maybe

ineffa for flins, bina for lauma.

Ineffa. Flins needs her more than he needs Columbina. And if you intend to play dps Columbina, she also needs Ineffa

If you really need to pick only one, then Ineffa. Flins Ineffa is stronger then Columbina Flins/Columbina Lauma, and Ineffa is a fantastic universal sub dps. I'd still advise to try to get Bina after tho.

ineffa is better for flins, arle, clorinde and probably alhaitham

columbina for lauma and skirk, maybe clorinde
