Skills needed: very precise sfrafing skills
Difficulty: hard, especially because of the monsters
Description:
This nice jump is useful in Pacifist skill. With it, you don't have to worry about the spectres/soldiers down in the dark. It's likely that it'll stay just in the Pacifist route, as the UV and NM routes have a faster jump already.
