1. I've got a PCer inside a Pulse Waver's range. Can I make the PWer re-roll the roll?

2. If you've got 2 victims within the Pulsewave's range but only one is hit, the damage from the PW is still reduced to 1, right?

1. no. PW ignores all powers, including those of freidnly figures.

2. yes. the figure's damage value becomes 1 during the drawing lines of fire part of the power, so if there are 2 or more figures in range, damage = 1

Thank you kindly, OpalScion.
