Poseidon - SHORT CUT -

A marathon-style shortcut with patterns focused on half-steps. While you can mash through it, the patterns are so simple that if you support the bar well with arm strength, you can easily handle it with precise hits. Compared to the single-step pattern of the same song's Single 21, there's a huge difference in accessibility; for those with strong stamina, this could even be considered a low-level chart.

If you mash it, the offbeat mashing layout makes it even more confusing, so playing it straight is actually easier. The pattern is regular, so once you get used to it, the perceived difficulty drops significantly.
