Gacha was annoying and I spent 350 orbs for the +1, one of them being sparked.
I got an spare Diamant and Brave Tiki for the Finish 4 and TP4 fodder so now she can precharge and continuously cycle Glacies.
She still benefits a lot of TR scaling via Resistance buffs so ideally you would give her those via Tactics.
This build of course doesn’t exploit her potential and support spreading bonuses.
Gacha’s been REALLY annoying in general all summer. I’ve been using every spare orb on the summer banners with only off-banner units to show for it. I’m getting really frustrated with it, but that’s what I can expect after going fully F2P since late last year.
