Avalanche

Mash through the beginning to survive, and even if your HP is low, if you clear the bracket drills first, you'll enter the late spike with full HP. It doesn't take as much stamina as you'd think, and the pattern is simple.

If you mash all the high-angle notes and follow the crossover movements reasonably well, your gauge will get shredded, but if you don't miss from the pause section after the compass chart and fill your gauge up to the early part of the late spike, you'll have enough gauge to survive the final twist-drop and crossover. It drains a lot of stamina, but I think other 25s are similar.

If you can't do the axis twist (alternating red-yellow-red) using the blue note as the axis, the difficulty spikes. The final bracket is also hard to interpret.

The chart is easy, but it drains way more stamina than Gargoyle.
