Effect: Target: Caster changes the result of a 2d6 for a spell use check made for a magic attack or for a hit check, adding a Modifier determined by the effectiveness score. If the new roll result is 12 or higher, it is treated as a 12, and the check is a critical success.

This effect is lost at the end of the caster’s turn, or once it has been used.

This spell can be used as a free action.
