Stat Priorities for E2 Sparkle Sub DPS for Silver Wolf

As the title mentioned, checking on the Stat Priorities (especially on maxing Atk% vs Speed Breakpoints vs using ERR Rope). On the top of my head, my prioritization is:

1. ERR Rope (More Ultimate = More Thrill Stacks)

2. Atk% (Get to Break Point)

3. Speed (Get to 134)

4. CV
