Blast:

A simple damaging spell, allows a character to use their Magic attribute for a single roll, instead of Prowess. Alternatively, during a duel and for an increased cost of one, this spell may be used to replace any one secondary attribute (Prowess, Cunning or Strategy) with Magic. This may be cast multiple times during a duel to replace other secondary attributes, but the cost increases by one each time. (3, then 4, then 5).
