Delayed Azure Bombardment

The Caster takes aim and fires off 8 beams of steam at a target. each beam that hits the target deals 1 fire damage and leaves a mark that the caster must keep track of. on the casters next turn they may activate those marks that were left by the steam to deal 1D6 fire damage per mark that was left. 

for every spell level of 4th or higher the caster may select one more target.
