The Smurfiest Wizard Ever!
I don't know if it applies because those are conditions. If you compare Charm Person for instance to Suggestion, Charm Person actually says the target is charmed ("If it fails the saving throw, it is charmed by you until the spell ends...") as where Suggestion never mentions it (except if you are immune to Charm). The target of Suggestion is not under the charmed condition, as where the target of Charm Person certainly is.
I could understand a DM ruling either way on that really, so not trying to be argumentative, just food for thought.
Yeah, certainly agree on that one.So why allow the save in the first place?
Your DM got that one wrong.
