Awkward 'B'-Gone

When you cast this spell, you skillfully reshape the memories of listeners in your immediate area, so that each creature of your choice within 5 feet of you forgets everything you said within the last 20 seconds. Those creatures then remember that you actually said the words you speak as the verbal component of the spell.

The last thing the target hears must be the statement to be erased. If a new person speaks to the target, before the spell is cast; Spell will no longer take effect.
