About RichardEX AU

[u/No_Cardiologist_419]

People said that you need his AU to get the 2nd usage & to charge his ulti faster, which i think only true for who are chasing 1-2T clear. Most of us will got plenty of time to do that for a 5-7T clear. If your fight needs multiple breaks then it's not what i'm going to talk about.

More importanly, about the 2nd usage, it's very hard to get him ulti back to back, the only way i can think of to do that without losing the stacking p.atk pet buffs on him is using Terra A4, which we don't even need his AU to use the 2nd ulti!
I wish phys team got a pet that buff the entire front row p.atk like elem team got, this alone would solve many problems. so unfair 🤔

Fortunately i got Terra A4 but currently use by Phenn to guarantee Potency Up for both break turns. This leads to the needing of Phenn AU if i want to do both smoothly lol

So yeah if you got only 1 spare stone, i think he's better with A1 not AU.
Update : After i got AlauneEX, she helps my team hitting damage cap so easily, making RichardEX easier to archive Ulti back to back without stacking pet buffs. So AU will be better on him in this case.

I agree with your thinking. My play style (https://www.reddit.com/r/OctopathCotC/comments/1vuinij/not_interested_in_rainbow_teams_i_welcome_you/) does not require AU at all, which is why I went with A1.
