Tharizdun's Maddening Scream

Choose one creature that you can see within range.

The target begins screaming, gibbering, and jumping up and down as though completely mad.

An affected creature cannot leave its space or take reactions, has disadvantage on attack rolls and Dexterity saves, and other creatures have advantage on attack rolls against it.

The target can use an action to attempt a Wisdom save to regain control of itself, ending the spell on a success.
