Jeff Jump
From SpeedSouls
Jeff Jump is a skip in Dark Souls II in which the player performs a precise jump onto the bridge in the gutter. It saves ~13 seconds
in runs which require jumping across for the branch and a bit less in other runs which do not require the branch.
It is named after runner JeffTheBigLizard, who first popularized the jump.
