Apparently, if you're diagonally behind a Mottled Ogre or Ogre Bruiser when they've finished changing their facing to use any of these 3 moves, you still get targeted. This is easiest to test in MM22-1.
@timeracers: You misunderstand. yyyy y^^y yOOy x___ _ = open square OO = Mottled Ogre ^^ = Direction Mottled Ogre is facing. y = Enemy MEANT to be targeted by Sweeping Smash. x = Friendly meant to NOT be targeted by Sweeping Smash. x is targeted and takes damage, anyway, even though the Ogre does not face x.
