You target one creature you can see within range, you cause all magic items carried by that creature to chaotically increase and decrease in weight. For the duration the creature suffers from the following effects:

Wobbling Wand: If the target creature attempts to use a magic item to cast a spell, they must first make a Dexterity saving throw or lose their action and drop the item without casting the spell.

Wild Weapons: If the target creature attempts to make an attack with a magic weapon and they miss, they drop the weapon and lose their action.

Heavy Hat: At the start of each turn, if a creature is wearing magical clothing or armor they must succeed on a Strength saving throw or are knocked prone.

At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, you make select an additional target for each spell level over 2nd.
