Drop Red signs out side Atorias or other boss fights (in the DLC areas), with the visual glitch a good chance they won't know you are a Red till it is to late.
i was there the other night and couldn't see any signs was only able to see the Summon option when i walked over one, i had no idea if it was Red/White/Gold
