Death potion

The is a custom potion, giving you all the negative potions effects of the game except for Darkness and Freezing. Despite all the effects, you will not die, at least immediately, since the effect that could kill you (Wither) gets overridden by the Poison effect, which cannot kill you. Still, the game will be unplayable, unless you have a Bucket of milk near you.
