Time period it is possessed for varies depending on its wisdom.

If alive:
The player has to roll 1D20 + Wisdom Modifier, if the outcome is (Enemy's Wisdom + Modifier) or higher then the body is possessed, if not then the spell slot is not used but the enemy takes 4d10 Psychic Damage.

If the possessed body kills any living creature, after the spell caster leaves the possessed body, the body would come back to life with 1 Hit Point, but if the body was already alive, then their hit points are not affected, even after being damaged in their possessed state.
