Dimir Charm

You power a sigil belonging to the guild of Dimir to create a magical effect. Choose one of the following when you cast this spell:

• You dampen the spellcasting of a creature of your choice you can see within range. Until the spell ends, the next time the target casts a spell or starts its turn concentrating on a spell, it must succeed on an Intelligence saving throw or end the spell and prevent its effect.
• You stab a creature within reach with a spike of negative energy. Make a melee spell attack against the target. The target takes 5d6 necrotic damage on hit, plus an additional 2d6 necrotic damage if the attack had advantage, and no damage on a miss.
• You scramble the senses of a creature of your choice you can see within range. The target must make a Wisdom saving throw. On a failed saving throw, the target can’t take reactions until the spell ends and on each of its turns, it must choose whether it gets a move, an action, or a bonus action; it gets only one of the three. The target can repeat the save at the end of each of its turns, ending the effect on a success.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, you may choose two of the spell's effects instead of one. When you use a spell slot of 8th level or higher, you may choose all three of the spell's effects instead of one.
