Effect: You can move 4 squares vertically and remain there, hovering above the ground. While aloft, you are unsteady, taking a –2 penalty to AC and Reflex defense. If some effect, such as a pit opening below you, causes you to be more than 4 squares above the ground, you drop down to 4 squares above the ground. You do not take damage from such a fall.
Sustain move: You can sustain this power until the end of the encounter or for 5 minutes. When you sustain this power, you can move 3 squares up or down or 1 square horizontally. You cannot go higher than 4 squares above the ground. If you don’t sustain the power, you descend to the ground without taking falling damage.
