I wouldn't roll it into a Power Modifier unless ALL spells require the same roll and all spells have no required roll to begin with. It gets messy otherwise.

The basic system only requires skill checks on spells that need to be aimed. The skill roll I want to know about would be added to all spells, it would representing the concentration it takes to shape the spell, and would be added in addition to the aim skill check on those spells.
