Hestia

Just a stamina run with standard twists.

it looks like a 20 and not much different than high-end 20s like hyperion - but it gives even less break time which ratchets up the difficulty to the point where the re-rate to 21 feels deserved

BPM 155 isn't exactly slow, but since the chart consistently emphasizes stairs, the instances of getting lost while reading the path have decreased significantly. The crossover at the very end is nearly impossible for locals to twist-step, and if you just fill your gauge as much as you can see, you can clear it even by leaking some notes. Since Tepris rose to D20, there's a reason for the level increase.
