Arrow of Pasting

When you make a successful ranged attack with this arrow the target must succeed on DC 15 Constitution saving throw or be turned into a Grey Ooze until the end of the target next turn. The Grey Ooze retains any mental stats it previously had and if it is reduced to 0 hit points it reverts back to its original form and takes any excessive damage the Ooze took.
