Wizkids Rules!

Both Arex and Geordi La Forge from the Fed vs Klingon starter pack reference the revealed maneuver.

Arex allows for turning the dial to a maneuver of the same revealed speed.

Geordi allows for increasing or decreasing the speed of the revealed maneuver.

If they are on the same ship, can they be used together? Or when one is used, is the maneuver no longer revealed, invalidating the timing of the other?

Both can be activated at the same time off of the same maneuver being revealed.

Arex acts as a replacement for the maneuver then Geordi modifies the maneuver selected by Arex.
