How-Tsu: Ice Dragon Asante - Tsu solo auto
Okay, maybe I am redoing the series, as I will try the remaining dragons.
As usual, Tsu's gear is Extreme Magic Bow, Monkey King Vest, her exclusive Shadow Star Cowl, and unlike the Aniki series, she has an Overlord's Badge, all with Breeze. Maxed bonds and casting (no casting skill until August), but my soldier training is incomplete (71/71/59 for HP/Atk/Def right now), and she's only 5 stars.
Skills are shown at the start of the video, but I'll put them here anyways: 1c Instant Flash, 2c Quick Step, and 2c Defense Intimidate.
As for the other dragons: Thunder Dragon Carcosta is 100% impossible to auto, and I'm almost positive she can't even solo it manually... but support from FB and like Almeda's cross-map heals did make Tsu be able to do 100% of the damage at least. Fire Dragon Fafnir, on the other hand, should be simple enough, maybe even doable on auto. At least the aoe units don't inflict passive silence like they did here lol, buff block does nothing to her besides block breeze buffs.
