Throw Up Creatures

Choose a creature that is Small or larger within range. That creature now throws up a tiny creature you specify for one minute, e.g. spiders, slugs, mice, etc. 

At the start of each of its turns, the creature has to make a Constitution saving throw. On a failed save, the creature is knocked prone and frightened and takes 2d8 poison damage. On a success, the creature is not knocked prone, takes no damage, but is still frightened. 

Each creature other than you within a 30ft. radius of the target that can see the target has to roll a Wisdom saving throw. On a failed save, a creature is frightened of the target as long as it can see the target. 

The tiny creatures that the target throws up are neutral to anyone, will not attack and flee when provoked or attacked.
