The caster reaches out and attempts to sever the connection between the target and the weave. The target must make a Constitution saving throw equal to the casters spell casting modifier.

If the target fails the saving throw, until the caster’s next turn they are rendered mundane. The target cannot cast spells, be affected by any spells they have cast upon themselves prior and lose the target loses concentration. The target may repeat the saving throw at the end of its turn. 

If the target succeeds the saving throw, the spell fails.
