I'm telling you guys, you're sleeping on this skill.
It's somewhat rare (I added a basic R Tamamo Cross just because it has it) and when it activates my uma always jumps forward, maybe because while the other Umas lose acceleration on ramps, my Uma actually GAINS so it's sorta like a double effect.

If you have this + Late Surger Savvy + some navigation skill + Rudolf's unique skill passed through breeding... You get yourself a pretty good late surger, more consistent than usual for sure.
