Oh wow lots of new news.
Most exciting ones for me are the QoL change in the UI, and also the silent notification of the arena change to bonus points for getting kills with the bonus hero. Now you only need to kill one enemy unit with the bonus hero, cheerleader meta is dead, thank goodness.
Book 4 looks trippy. Might be fun? Aesthetically speaking, it looks super generic fantasy anime gacha-y, but the art's pretty gorgeous so I'll give it points.
Also Close Call 3 sounds nuts, I love it.
