    Personal, 1 round/level. Cold or fire based flames - 5M light, and
    1d6 + 1 per caster level in appropriate damage. Also, half damage versus
    the opposite colour chosen (choose fire shield, get 50% cold immunity).
//:://////////////////////////////////////////////
//:: Spell Effects Applied / Notes
//:://////////////////////////////////////////////
    No Evasion thing here,  at the moment.

    May add later, if we split up GetReflexAdjustedDamage

    Anyway, 2 shields, subdial choice. One spell.
