The specifics of potions

Potions that can't be brewed-

The Potion of Luck[Java Edition only] and the Potion of Decay[Bedrock Edition only] cannot be brewed and can only be found as treasure or given by commands.

Potions that can be obtained from mobs/chests-

Battling-

• Witches can drop potions of Healing, Fire Resistance, Swiftness, or Water Breathing if they die while drinking that potion.

• Piglins may barter a potion or a splash potion of Fire Resistance when given a gold ingot.

• Wandering traders have a chance to drop a Potion of Invisibility if they die while drinking the potion.

Fishing: Water bottles can be fished up as junk items.

Two Health II potions can be found in the brewing stand on ships in end cities, and one splash potion of Weakness can be found in a brewing stand in igloo basements.

In Bedrock Edition, the cauldron in a swamp hut contains a random potion.

Potion of Regenerations can be found in Ancient City and Buried treasure chests.

Potion of Water Breathing can be found in Buried treasure chests.

Usage of Potions-

Potions are used by pressing and holding use with the potion bottle in hand, as with all consumable items. When drunk they bestow the corresponding status effect to the player.

Modifiers-

Potions can be modified in five ways.

1- Brewing glowstone dust into certain potions will enhance their level of effect.

2- Adding redstone will extend the duration of the effect.

3- Brewing gunpowder into a potion makes it into a splash potion (area effect).

4- Adding dragon's breath to a splash potion creates a lingering potion (area effect that lingers on the ground).

5- Brewing a fermented spider eye into specific potions modifies their effect, usually inverting it, which is referred to as "corruption".

Corruption:

The usual result of corruption is to invert the potion's effect (for example Swiftness becomes Slowness). Interestingly, corrupting Poison (continuous damage effect) creates a Potion of Harming, an instant damage effect, instead of the continuous healing effect (regeneration) one would normally expect. Corrupting a Potion of Night Vision turns it into a Potion of Invisibility rather than an inverse effect that might be something like blindness.

Water Bottles are the base for the Awkward Potion and Potions of Weakness

Awkward Potions are the base for all other effect potions

Mundane Potions are only usable as an alternative base for Potion of Weakness [Bedrock Edition only]
