# Magic Duel : each side gets to add his astral skill to a (not open ended) d6. Ties result in the death of both mages.
A +3 differential gives you a 1 to 6 odd. +5 gives you a 100% chance of killing the opponent but you still die about 3% of the time, and you have to be 6 levels higher to always win and never die.
Magic Duels use base astral levels, spells and items do not seem to have any influence.
There is no saving throw. This is an area effect spell (1 square), so you better disperse your astral mages. Mages without astral magic are unaffected.

4+d6 -> 5 to 10
9+d6 -> 10 to 15
