You attempt to reflect a spell back onto its caster in the process if casting this spell. If the spell is of 6th level, the spell is immediately reflect back onto them. If the spell is of 7th level or higher, you and the target must make opposed ability checks using your spell casting ability modifier.  On a successful ability check, the spell is reflected back onto its caster. On a failed ability check, the spell resumes as usual.
