With their Camouflage ability Wendigos can turn themselves invisible if they spend 5PPs and make a Hard SD all or nothing maneuver...
Now, Wendigo SD bonus is +8, which means that they have to spend 5PPs andmake a all or nothing maneuver adding a total bonus of -4 (16 for SD x2 -20 because it's a Hard maneuver) to the roll...
I'm doing something wrong? How can they ever hope to activate their ability, save by a stroke of luck?
