Argal gets the rest of the party up and manifests a power to boost his speed. He makes a running leap on top of the nearest building, but doesn't allow himself to drop down. Might make too much noise. Instead, he uses levitation to stop himself in the air just before he hits the roof. He then takes a low profile and looks around the streets.

Manifesting Burst. It gives me a +10ft speed bonus, but the main use is that the speed bonus also translates to a +4 to jump checks.
