Lingering Potion

Lingering potions are variants of splash potions that can be thrown to leave clouds with status effects that linger on the ground.

Creating potion clouds
Lingering potions are thrown, like splash potions, by them. On impact they explode, creating a cloud. The cloud is made of the potion particles corresponding to the potion that was thrown.

The cloud starts with a radius of 3 blocks, decreasing to 0 over the course of 30 seconds. During the cloud's existence, any player or mob that walks into it after the first second gets the corresponding status effect; this decreases the radius by a $1/2$ block immediately, causing the cloud to disappear more quickly.

For effects with duration, the duration applied by the cloud is $1/4$ that of the corresponding potion. For effects without duration such as Healing or Harming, the potency of the effect is $1/2$ that of the corresponding potion.

The effect may be applied consecutively if the player or mob remains in the cloud. For example, a player throwing a Lingering Potion of Healing II straight down consumes the cloud within a few seconds while being healed 5 times for a total of health. As far as healing is concerned, this makes the lingering potion much more powerful than the regular or splash potion, provided that the player is away from other mobs or players.

Lingering potions can also be thrown out of dispensers just like splash potions.

Filling cauldrons
$$, using a lingering potion on a cauldron adds one level of that potion to the cauldron. Attempting to add a lingering potion to a cauldron with water, dyed water or a non-matching potion empties the cauldron and creates an explosion sound (but no actual explosion).

Uncraftable Lingering Potion
$$, the uncraftable potion is a splash potion with no effect that is unobtainable in regular gameplay. It is also available in potion and splash potion forms, as well as for tipped arrows.

It can be obtained using the following command:. It is also obtained any time a potion has invalid or missing potion effect tags, and thus serves as a placeholder.

Custom effects
$$, lingering potions can be obtained with any status effect using and the tag , which is an array of effects for the potion. See Item format for more information, and status effect for a list of effects and IDs.
