Almost Near About Instant Death But Not Really

The caster points at the target they wish to effect and draw a circle in the air while chanting "hamana j mari jao mari jao". At first level, the spell causes the recipient to look as though they have fallen to the ground in pain and anguish, those watching must roll a DC 18 wisdom check. When succeeded, they immediately see the invisible subject and know that it was an illusion. When failed they believe that that subject just nearly died. In actuality that person is still perfectly fine and is invisible while still able to take actions at full movement speed and full damage.
