Features

Zauber Cauldrons are an expansion to the game's magic system, allowing the creation of stronger potions, magical armor, effect granting crystals, and bottled wormholes. Several features in this module are dependent on the world seed, changing recipes and encouraging players to experimentally discover exactly how to use the most powerful mechanics.

Creation

A Zauber Cauldron with some steam coming off of it.

A Zauber Cauldron is created by "bespelling a boiling cauldron by reading out of a spell book". Any water-filled cauldron with fire below it can be used, and any enchanted book will suffice. To "read" from the spell book, simply hold the enchanted book and stand next to the cauldron. The cauldron will begin to give off steam, indicating the newly formed Zauber Cauldron is ready for use.

Recipes

All Zauber Cauldron recipes are performed by dropping items into the cauldron. Once the proper ingredients are inside, the resulting item will form, consuming the ingredients and some water. To assist in the process, a player looking at a Zauber Cauldron will be unable to pick up items inside the cauldron until they look away.

Substrates and Solvents

When crafting with a Zauber Cauldron two substrates are of particular importance: Water, and Powder Snow.

	Water is a good choice for most recipes, but can't contain highly exothermic recipes like Strength IV or Splash or Lingering potions, leading to mostly destructive results.
	Powder Snow will inhibit most recipes from completing, however, it may be used to contain highly exothermic recipes. Therefore Powder Snow allows for the creation of Splash and Lingering variants of tier IV potions, without triggering an explosion.

Potions

All craftable tier IV potions.

Zauber Cauldrons can be used to strengthen any Tier II potion into a Tier IV potion. This recipe requires Prismarine Crystals, a Golden Apple, and a Tier II Potion.

Be cautious when performing these recipes. They all have a side effect, either to the recipe process or to the effects of the potion.

Potion Recipes

Product	Recipe (Zauber Cauldron)	Ingredients	Side Effects
Potion of Strength IV (1:30)		Potion of Strength II + Golden Apple + Prismarine Crystals	Ignites the area around the cauldron. This can be prevented by the use powder snow instead of water.
Potion of Regeneration IV (0:22)		Potion of Regeneration II + Golden Apple + Prismarine Crystals	Potion gains Speed III (0:16) Emits a lingering wither cloud
Potion of Swiftness IV (3:20)		Potion of Swiftness II + Golden Apple + Prismarine Crystals	Potion gains Weakness IV (6:00)
Potion of Healing IV		Potion of Healing II + Golden Apple + Prismarine Crystals	Potion gains Nausea (0:08) Emits a lingering death cloud
Potion of Poison IV (0:32)		Potion of Poison II + Golden Apple + Prismarine Crystals	Summons cave spiders and cobwebs
Potion of Leaping IV (1:30)		Potion of Leaping II + Golden Apple + Prismarine Crystals	Summons a Killer Rabbit
Potion of Harming IV		Potion of Harming II + Golden Apple + Prismarine Crystals	Emits a lingering healing cloud
none		Any Splash or Lingering Potion + Golden Apple + Prismarine Crystals	The Zauber Cauldron explodes, unless powder snow is used; In which the recipe results in a potion identical to the drinkable version but as a lingering or splash variant.

Advanced Reactants

Many advanced Zauber Cauldron recipes use "Enchanted Prismarine Shards" as an ingredient. Enchanting a Prismarine Shard requires 30 levels of experience.

Extraneous Ingredients

If any unneeded ingredients are added to a Zauber Cauldron during a crafting process, they will be transformed into "Possessed Items" — weaponless Vexes that pester the player before dying a few seconds later. Each excess item entity in the cauldron transforms into a single Possessed Item.

Possessed Items can be caught and stored by adding a glass bottle to the Zauber Cauldron, forming "Magic in a Bottle". These bottles are only stable if they contain a multiple of three Possessed Items, and will immediately shatter and release the Vexes contained within if this condition is not met. Otherwise stable Bottles of Magic also become unstable if they are left on the ground for too long, releasing the contained Vexes.

A set of Zauber Armor. Usage of mending and unbreaking is highly recommended.

Armor

Zauber Cauldrons can be used to infuse golden armor with certain items, forming "Zauber Armor". This gives the armor an extra effect and boosts its defense. This recipe requires any piece of Golden Armor, an Enchanted Prismarine Shard, and a Modifier Item corresponding to the desired armor effect.

The infusion process doesn't destroy enchantments or lore on the armor piece, but can't be done on a piece of armor that's already been converted into Zauber Armor.

Every piece of Zauber Armor also holds a decorative Attribute Called "+25% Magic."

Armor Modifiers

Modifier	Effect
Glistering Melon Slice	+4 Max Health (2 Hearts)
Blaze Powder	+35% Attack Damage
Sugar	+12% Speed
Turtle Shell	+1 Armor

Upgrading Golden Armor to Zauber Armor greatly improves its defense rating. A full set of normal Golden Armor gives the player 11 defense points, while a full set of Zauber Armor gives the player 17 defense points. This is about a 55% increase in defense. Additionally, each piece of Zauber Armor has an armor toughness of 3, heavily reducing damage from high-damaging attacks.

Zauber Armor Defense Values

Armor Piece	Armor Value	Armor Toughness Value
Helmet	+3 Armor	+3 Armor Toughness
Chestplate	+7 Armor	+3 Armor Toughness
Leggings	+5 Armor	+3 Armor Toughness
Boots	+2 Armor	+3 Armor Toughness
Full Set	+17 Armor	+12 Armor Toughness
	Set Bonus activates

Set Bonuses

When wearing a full set of Zauber Armor, the armor flavor that the player is wearing the most pieces of gets a virtual boost of one piece. This even applies if there is no prevalent flavor, but instead the number one spot is tied. In that case both flavors receive said boost.

Crystals

Crystals are an advanced alternative to potions that provide continual tier II status effects. This recipe requires a Sea Lantern, a Nether Star, and a Protection IV Enchanted Book.

Crystals are active when in the player's off-hand and require the Luck Effect

Crystal Recipes

Product	Recipe (Zauber Cauldron)	Ingredients	Effect
Crystal of Strength		Sea Lantern + Strength IV Potion + Nether Star	Strength II, Fire Resistance
Crystal of Regeneration		Sea Lantern + Regeneration IV Potion + Nether Star	Regeneration II
Crystal of Swiftness		Sea Lantern + Swiftness IV Potion + Nether Star	Speed II, Weakness II
Crystal of Healing		Sea Lantern + Instant Health IV Potion + Nether Star	Instant Health II, Nausea
Crystal of Poison		Sea Lantern + Poison IV Potion + Nether Star	Poison II
Crystal of Leaping		Sea Lantern + Leaping IV Potion + Nether Star	Jump Boost II
Crystal of Harming		Sea Lantern + Harming IV Potion + Nether Star	Harming II

Luck

The Luck status effect, required for Zauber Crystals to function, can be obtained from a recipe involving "lucky" flowers. This recipe is seed-specific, and will vary from world-to-world, requiring the players to experiment and discover the ingredients themselves.

Each of the 12 small flowers will either be "lucky" or "poisonous", and in order for the recipe to grant the luck effect, all the "lucky" flowers must be thrown into a Zauber Cauldron along with an Enchanted Prismarine Shard and, as the last item, a piece of cut Grass. If performed successfully, nearby players will be granted with a permanent Luck effect that lasts until death.

Product	Recipe (Zauber Cauldron)	Ingredients
Luck		All Lucky Flowers + Enchanted Prismarine Shard + Grass

If some of the lucky flowers are missing from the recipe, then nothing will happen and the ingredients can be retrieved. However, if a poisonous flower is added to the recipe, the cauldron will instead emit a poisonous cloud and transform all ingredients into Possessed Items.

By experimenting with each flower individually, one can determine which flowers are lucky and which are poisonous by recording which ones emit poison clouds when added to the recipe.

Wormhole in a Bottle

Zauber Cauldrons can be used to create a powerful potion, the "Wormhole in a Bottle", that can teleport the drinker great distances instantly - even across dimensions. This recipe depends on the world-seed, and will be different for every world, encouraging the players to experimentally figure out the details of the ingredients.

This recipe requires an Enchanted Prismarine Shard, Magic in a Bottle, and some quantity of both Chorus Fruit and Popped Chorus Fruit. The destination of the wormhole will match the location where the vexes contained within the Magic in a Bottle were caught. The precise quantity of the Chorus and Popped Chorus Fruit changes from world-to-world, but will be between 1 and 64 for each.

Product	Recipe (Zauber Cauldron)	Ingredients
Wormhole in a Bottle		Enchanted Prismarine Shard + Popped Chorus Fruit + Chorus Fruit + Magic in a Bottle

Wormholes explode when the drinker reaches their destination, damaging surrounding blocks but not harming the player. This explosion can be contained if the destination is within a Zauber Cauldron. In practice this means the cauldron used to create the Magic in a Bottle shouldn't be removed without blast-proofing the surrounding area.

If too few Chorus or Popped Chorus are used in the recipe, the resulting Wormhole will be "blurry", teleporting the player to random nearby location. Since this new location will likely not be inside a Zauber Cauldron, consuming the potion will usually cause an explosion at the destination.

If too many Chorus or Popped Chorus are used, the excess fruit will transform into Possessed Items which will attack the player. The Wormhole will be perfectly precise however, without any randomness in its destination.

The precise amount of Chorus Fruit, the quantities that will neither create a blurry wormhole nor summon vexes, can be determined via experimentation and testing. One common experimental method involves counting the number of Possessed Items that are summoned, which is the number of excess Chorus Fruit that was used, and reducing the input number of fruit by that quantity until a precise Wormhole is produced.

Soul Fire

Heating a Zauber Cauldron with Soul Fire instead of ordinary Fire will alter the nature of any potion created by the cauldron, allowing a single bottle to be consumed multiple times. These "Soulutions" contain 9 doses of whatever their effect is.

Technical Details

Potion Clouds

The wither cloud produced from a Regeneration IV potion is 1.8 blocks in radius, and will slowly shrink to nothing in 7.5 minutes. It inflicts a Wither 6 for 64 seconds and Instant Damage 2 every 2 seconds. Each dose consumes 0.01 of the clouds radius, meaning 180 entities would need to enter the cloud to fully consume it before it dissipates.

The death cloud produced from a Healing IV potion is 2.1 blocks in radius, and shrinks to nothing over the course of 3.5 minutes. It inflicts Instant Damage 9 for 2 seconds, or 54 health (27 hearts) of damage every tick for 40 ticks. To survive the effect the player would require 1080 hearts in total. The cloud has 3 doses of potion, meaning it can kill 3 mobs before dissipating.

The healing cloud produced from a Harming IV potion is 1.25 blocks in radius, and does not shrink. It grants Instant Healing 3 (6 hearts) every second, and has 14 doses of potion, after which the cloud disappears.

Crafting Optimizations

Crafting checks are ran in stages to minimize passive lag:

First off, only Cauldrons with a valid structure - meaning a fire block beneath and water - are considered valid for crafting checks.

Once the module has found a Zauber Cauldron that's ready for crafting checks, the module checks for so called "identifier Items". These are items that are unique to a recipe category, e.g. prismarine crystals for the Category "potions". Once such an item is found the module will start to go through all the entries for a recipe Category. These are specified within the <category folder/<category name>.mcfunction, E.g. Potions/Zauber_Potions.mcfuntion. At this point the function checks for a second order identifier item, e.g. a speed potion, which is again unique within the category. Once that is found a function unique for the actual recipe checks for all the items that all recipes of the category have in common (e.g. golden apples for potion recipes) and then summons the output item.

Wormhole Blurriness

A blurry wormhole shifts the destination coordinates by adding random numbers to each coordinate. Typically, the coordinates remain within 12 blocks of the original cauldron coordinates, but in theory could be shifted as far 99 blocks in any given direction.

Previous Versions

MC 1.11-1.12 Versions

Many features of this modules have been changed over time. Prior to 1.13, the module did not have Wormholes, Magic in a Bottle, Possessed Items, or Soul Potions. The Luck Recipe required the player to be wearing full Zauber Armor, and did not change with the world seed. Instead, the duration of the luck effect depended on the number of flowers thrown into the cauldron. With all 10 flowers, the luck would last 100 minutes. Crystals would also function from anywhere in the players inventory.^{Citation Needed}

Pre-1.13 versions of Zauber Cauldrons employed an additional step in the one-click installation where the user needed to click a sign. This was used as part of a workaround to get the section sign into certain command blocks, allowing for lore to be formatted and colored to appear as if it were potion effect information and attributes.

There also existed an additional version of Zauber Cauldrons exclusive to the Hermitcraft GM4 server, which contained features such as Haste Potions, Blood Moons, and a series of Magic Swords.
