VANISH

You need a high level of both bracket skills and run ability. It feels way too underrated to be placed in the mid-high tier. While there are clear potion sections, it won't be easy to survive the late spike without skill, regardless of your gauge, especially when your stamina is drained.

This is at least an 18 for a 4-note AD chart, the runs and twists are mid-18 level

Even if it were just pure raw runs, the stamina drain alone would make it a solid 17. However, since it has a high proportion of twists and requires bracket handling, I think it's on the harder side of 17s.
