Dear Professor, After the maintenance on July 25th, Souchun and Daiyan's Arma Inscripta "Emerald Abundance" and "Stringbound Sentiment" will be available! And they're both really good!
Souchun(Arma.Inscripta.Emerald_Abundance){ //Souchun gets enough of an upgrade to stand out next to Croque.
At AI1, Souchun gets a much-needed buff to her passive. Her max hp increase and hp recovery will both happen a lot faster and more reliably. But it gets better.
At AI2 her healing increases even more and her auto skill gets a much bigger range.
Finally, at AI3 she gets the counter enemy normal attacks with a [Bind] cc debuff. };
Daiyan(Arma.Inscripta.Stringbound_Sentiment){ //This one is just ridiculous. YZ is clearly playing favorites here.
At AI1 Daiyan's soundwaves now buff the ATK and Hashrate of allied units to pass through. I hope I don't need to explain why this is insane. But it's also just the start.
AI2 changes Daiyan's auto skill. Her [Concordia] status effect is upgraded to [Concordia+]. On top of its prior effect, Allied units whose skills can already crit now get boosted crit damage. And the buff is immediately applied to all allies on activation. Positioning shenanigans no longer required.
Finally at AI3, when allies with the Concordia+ buff do crit damage with their skills, the ultimate gauge refills faster. };
Both of these upgrades are actually really good. But one is just broken. And it's not Souchun.
