I command the Ethereal to Repulse this being.
This spell causes a Being to have to stay ten feet away from the caster for the duration of the spell, so long as the caster holds his hand palm upward toward them.
The Caster may once this spell is cast other spells and the Being may choose to wander off or remain and wait out the duration of the spell, but must stay at least ten feet away from the caster.
If the Being is closer than ten feet when this spell is cast they must back up to that distance, before they may defend themselves or attack anything else.
If the Caster walks forward the Being, must continue to walk back, always staying at least 10 feet away.
