Hello all!
Would love some clarification on this.
The Authoritative spell metamagic states the following:
'You can alter any spell that targets a single creature to become an authoritative spell. When you cast an authoritative spell, choose one of the following activities to prohibit: move closer to you, move away from you, make a melee weapon attack, make a ranged weapon attack, cast an offensive spell, or cast a non-offensive spell.
A creature that is affected by the spell and fails its saving throw against that spell (if the spell allows a saving throw to resist) cannot perform any action of the selected type on its next turn. An authoritative spell gains the lawful descriptor, and the additional effect is a mind-affecting compulsion effect.'
My magus used a shocking grasp with a lesser rod of this thematically fun metamagic to prevent a big scary creature from moving away from me to chase our summoner down. Our DM wanted clarification as the group had a mini debate on whether it has to be used with a spell that has a saving throw attached or if it can be used with a spell with no save and thus, would automatically work (assuming the creature can be subjected to a mind-affecting compulsion effect.
Any official statement would be perfect but also a community vibe would be appreciated :)
Many thanks all!
