    Notes:
    
      -  Radiation Spells  have effect throughout their specified Radius, and 
      deteriorate at minus or plus one LI (for Light and Darkness respectively) 
      beyond that Radius for further equal distances, down to LI+1/-1. The Radiation is distributed throughout the 
      initial Radius. It does not shine / darken through major obstacles such as
      walls, but does shine / darken around minor obstacles such as bodies, creating  shadows 
      only outside the initial Radius.  When cast on objects (Items) they may be covered over to block
      the Radiation as if the cover were a major obstacle.
-  Light and Darkness are opposites which cancel each
      other out, but multiple Light sources are not cumulative, nor are multiple
      Darkness sources. To calculate the current LI at any given point start at
      LI 0, add the strongest Light source, and subtract the strongest Darkness
      source. The exceptions to this are lanterns, torches and fires
      underground, which dispel up to two LI of shadow, but do not dispel
      Darkness Spells.
-  Coloured Lights mix colour in proportion to their
      relative intensity, but are not otherwise cumulative.
- The full effects of Light and Darkness are as stated in the Light
        and Darkness section of the Thief System.
