If the other person on Earth getting m6 Orphie is here, I have done some testing on basic links in the crappy Seed event where they attack you back and make it difficult.
>dash attack -> ba3 (important)
>dodge counter -> ba3
>def assist -> ba3
>ba5 -> dash attack
>chain attack -> dash attack
>corrosive flash -> dash attack
>watch your step -> ba5, which is what it says in the description
>crimson vortex -> ba1; i.e., nothing
I didn't check for heat charge and ult since it's not worth keeping her in after using them.
For anyone who didn't read m6, the reason this matters because crimson vortex does triple the damage of watch your step, generates the same heat, but it has to be used after ba5 (which also newly generates heat at m6)
