Create Pariah

You reach towards a creature within range and place a twisted ward around them, preventing assistance from finding its mark on your target. The target must make a charisma saving throw, on a success, nothing happens, on a failure, the target is marked as a pariah. While a creature is marked in such a way, no ally can target or include them within a spell of 3rd level or lower, and all spells cast on this creature by an ally of 3rd level or lower automatically end (specifically, the effect ends on the marked creature, but is maintained for any other targets of the spell). The marked creature also cannot benefit from any feature of any magic item of a rarity of uncommon or lower if the feature requires an action, bonus action, or reaction by themselves or an ally to activate. Finally, if any given ally is of 7th level or lower, or has a CR of 7 or lower, that ally cannot target or include the marked creature with any racial or class features, the ally cannot willingly move within 5 feet of the marked creature and on its turn must immediately use its movement to leave the area if safe, and the marked target is considered deaf to the effected allies.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the level of the spells nullified by this spell increase by one, and the level/CR threshold of the allies increases by 2 for each slot level above 4th. Additionally, if this spell is cast at a 7th level, the magic items effected by this spell are now of a rarity of rare or lower, and at 9th level are of very rare or lower.
