The shoe pebble

This spell causes a creature in sight to believe that they are constantly stepping on a really annoying pebble.

This curse will be dispelled at the end of one day.

This spell makes it so the creature that is affected by it always has to roll with disadvantage on any throw including saving throws. 

The creature affected by this spell constantly is getting more and more annoyed by each turn even standing still, is still affected by the pebble and its disadvantage due to pure hatred. This spell is still active with shoes or without. Without shoes it feels as if you are stepping on a singular pebble in the most annoying part of the foot. With a shoe it feels as if there is a pebble in your shoe always moving around.
