Java Edition:Infinite Duration Effects
Normally, infinite status effects are impossible to obtain via normal gameplay. However, they were available in both the snapshot that introduced infinite effects and the April Fools' version 23w13a_or_b.
Obtaining
23w05a
In 23w05a (a 1.19.4 snapshot), infinite status effects were introduced. These status effects have a duration of -1, and were not meant to be obtainable through normal game play as status effects are meant to end when their duration hits 0. However, a bug existed that would allow this value to decrease beyond -1. Since 1.15.2 Pre-Release 1, when a higher level status effect is applied over a lower level with a higher duration, the lower level will be retained. The lower level will continue to decrease its duration as the higher level effect decreases. However, if the higher level status effect is applied again with a duration longer than the lower level, the lower level can reach a duration lower than the higher level. Before this snapshot, the duration would stop decreasing at 0, but as -1 was added as a valid duration, it will tick down once more to -1. When the higher level status effect ends, the infinite effect will be applied.
In practical terms, this means the following must be performed:
- If the higher level status effect has a duration shorter than the lower level effect:
- Apply the lower level status effect
- Apply the higher level status effect
- Apply the higher level status effect again when the duration of the lower level status effect is lower than the duration of the higher level status effect
- When the higher level status effect ends, the lower effect will be infinite.
- If the higher level status effect has a duration higher than the lower level effect:
- Apply the higher level status effect
- Apply the lower level status effect when the duration of the higher level status effect is lower than the duration of the lower level status effect
- Apply the higher level status effect
- When the higher level status effect ends, the lower effect will be infinite.
Many of these effects may be applied to any entity that can have status effects applied. Creepers are particularly useful as when a creeper explodes with status effects applied, an area effect cloud will be created that applies the effects the creeper had. This mechanic can be used to apply infinite effects to entities in future versions and can be applied to more creepers, essentially duplicating the effects to more entities.
Due to the version constraints and available level for each effect, not all effects and levels can become infinite[1]. For brevity, discontinued effect sources are not included unless they are necessary for a certain level or effect. See the table below:

23w13a_or_b
In the April Fools' snapshot 23w13a_or_b, the perma_effect vote could apply a random non-instant (instant effects are Instant Damage, Instant Health, and Saturation) status effect with a random level from 2 to 6. This includes the normally unobtainable status effects Luck and Bad Luck. This also allows for the big and small effects, and at levels higher than the potions provide the player. When the vote is accepted, the status effect will be applied with an infinite duration to any player online. These effects, once applied, could then be made into potions by drinking the "bottle of void" item, which would store the most recent status effect the player had applied. The bottle of void must be first unlocked with the drink_air vote, where they can then be made by drinking glass bottles. As long as the perma_effect vote is active, their status effects will be reapplied upon relog, so one can quite easily farm for potions with infinite effects.
Unlike 23w05a infinite effects, these can only be applied to players as the bottled potions cannot be brewed into splash or lingering variants.
