Curse of Mundane Afflictions

You force one creature to make a Wisdom save. On a failed save you curse the target with a mundane affliction, a simple malady to annoy, distress or aggravate the target of your ire. Examples curses are:

• A Bad Night's Sleep. The creature has disadvantage on the first ability check it makes each day.
• Cramping Curse. The creature has disadvantage on the first attack roll it makes each day.
• Curse of Flat Ale. Any alcohol consumed by the creature tastes flat and unappealing.

Only one curse can affect a single creature. If the creature would be affected by any other curse, this curse ends. At 5th level the curse lasts for 1 week, 1 month at 11th level, 1 year at 15th, and at 20th level the curse lasts until it is removed.
