Rain is similarly harmful, but only inflicts 1 necrotic damage per turn. If this damage reduces you to less than half of your maximum hit points, you are considered to be poisend until your hit points are restored to over half your hit point maximum. Finally, if you are reduced to 0 hit points by this trait you die.
