I have Onatel at 3/70 and now Vivica at 2/60. I have no orbs. But when I get four would it be better to max Onatel or push Vivica?
Definitely depends on what else you have. I don’t have Vivica, but I do have (and LOVE) Onatel. Mine is approaching 3^70, and her special already makes her as valuable - maybe more - than most 4-star yellows. That means, in my experience, she doesn’t have to be maxed to be really useful, so you might consider boosting Vivica with your next four orbs. But in my case, I have two maxed 4-star healers already - Sabina and Melendor - and my next best yellow option is a maxed Danzaburo, so heck yeah I’m maxing Onatel SO GIVE ME THE DANG DARTS ALREADY, RNG! hehe.
I am in the same boat as @Danfink3 except my Onatel is maxed. She is great.
One note about her. At 3/70 she works well on offense but on defense I found her not as effective. I see a difference now with her being maxed and use her as my tank. I have Khiona next to her to give her an attack boost.
This is important, as I’ve been trying to decide when to switch my defense team’s tank from Danzaburo to Onatel. Still hanging with the badger for now, and based on your comment, I may consider doing so a bit longer. The AI will certainly screw up using Onatel’s special, and while Danza’s is unpredictable, the two useful results are both applied to all, so it’s impossible for the AI to screw it up.
I was using Lianna before Onatel as I have never really had a true tank.
