When you use Phase Sprint or Walk Through Walls, you can choose to significantly damage normal matter around you with a blast of transdimensional energy when you first go into or come out of phase (your choice). This detonation inflicts 4 points of damage that ignores Armor to all creatures and objects within immediate range. If you apply Effort to increase the damage rather than ease the task, you deal 2 additional points of damage per level of Effort (instead of 3 points); targets in the area take 1 point of damage even if you fail the attack roll.
