By directing your vectored thrusters all around your
mecha, you can kick up a cloud of dust and debris that obscures the battlefield.
Benefit: You can aim your thruster exhaust toward the ground to create a hemispherical cloud. If you are within 30 feet of the ground and there is loose debris or dust, you can create a cloud with a 50-foot radius centered directly below you. The generated winds snuff out small fires and give guided missiles attacking you a -4 penalty on their
attack rolls. Creatures without eye protection caught within the debris cloud are blinded while inside it and for 1 round after emerging from it. The debris cloud grants anyone inside it one-half concealment (20% miss chance).
Mecha with
sensor systems ignore the concealment effects.
