Because Mihobo decides to put random shit in the game, as in Seele not getting her intended SP back when you refresh your ult on the cross, I had to readapt. While doing that, I encountered something weird.
Turns out, there is more random bullshit in this stage: If you dodge the cross explosion with Seele, there is a chance to get GIGA SP recovery. In very rare occasions, this can boost HRB's SP up to 180. But even a bit lower is already enough to instant ult again later. So I changed my rotation for this and got 825 points.
There was only one thing left: how can I prevent HRB's next QTE after that whole cross phase to do a full ult again. But thankfully, dalao Akayuki showed a way in his video how to do that. The damage from S1 Dreamweaver at this disturbance is good enough to one-rot phase 2.
Higher ranks can outscore me "easy" tho. They still have to roll for that stupid RNG, but I am still glad I figured most of the run out myself - besides the QTE thing.
