Mucus ad Nauseam Tria
Mucus ad Nauseam Tria is a curse used to give a target a cold that increases in severity with each consecutive cast.
If the Uno or Duo modifiers are used in addition to this variation, then the version of the spell with the highest power will take effect. A single cast of this curse is only as powerful as Mucus ad Nauseam Uno, but what makes this variation of the Curse of the Bogies unique, is that unlike the Uno or Duo variations, each consecutive cast of the Tria variation will cause the target's cold to become more severe by a factor of how effective the cold was for the first cast (for example, a cold brought on by three casts of the curse will be three times more severe than a cold given by only one cast of the curse). There does not appear to be a limit to how many times this curse can be recast and increasingly affects the target.
