if say Nimrod does a pulsewave attack

1 step away from a building

and say black panther is 1 step away from the edge

will the pulsewave still hit him? or does it not go over roofs

No. The attack will only hit figures on the same elevation.

darn/mn/ng/mm! that was a quick reply!

thanks manh

Actually, you can hit figures on different elevations with Pulse Wave, but you must be able to draw a LOF.

In the above scenario, Black Panther is not on the edge of the roof, so a LOF can't be draw and he is safe. If BP was instead on the edge of the roof, and Nimord was in a position to draw a LOF to BP, then the Pulse Wave could indeed hit him.
