It takes a lot of stamina and the brackets are so annoying.

It's a check on how much stamina and gauge you can preserve in the easy patterns. There are no clear potion sections, but there are parts in between where you can just mash to save energy, so I don't think it goes up to high-level.

There are no forced placements, but it's a chart with a very honest pattern that still demands a significant amount of stamina. It feels somewhere between mid-high and high, but since I personally cleared it late, I'll give it a high.
