Ars Ocultas guide for All the Mods 10: To the Sky 1.0 to 1.8

Same as in the All the Mods 10 4.5 guide

Ars Ocultas is a small compatibility mod that connects Ars Nouveau and Occultism. If you use both of those mods, this is the bridge between them. This pack ships version 2.1.0, and it has been in the pack since version 2.2 or earlier.^[1][2]

What it does

The big idea is that Occultism spirits can now work from Containment Jars. Here is what the mod's project page lists:^[1]

• A spirit in a jar automatically pulls in items from a 7x7 area around it and processes them.^[1]
• You can also right-click items on the jar to process them yourself.^[1]
• A jar holding a spirit has an item capability, so you can pipe items into it. Pipes, hoppers and starbuncles all work.^[1]
• Janitor Spirits have a special behavior: they automatically try to push their contents into an inventory placed on top of the jar.^[1]
• The mod also adds new recipes to make progression easier, plus some quality-of-life changes.^[1]

Who it is for

This is for you if you want to automate Occultism spirit work with Ars Nouveau's tools and logistics. Jars can be fed by pipes, hoppers and starbuncles, so they fit into an automated setup.^[1]

Where it fits in progression

Unverified The sources I was given do not place this mod on the ATM Star path and do not mention any quests for it. The project page also points to an Ars Ocultas section in the Ars Nouveau guidebook, but I could not confirm that entry in this pack. Check in-game before relying on it.

Ars Ocultas is a bridge between Ars Nouveau and Occultism. Its main trick is that spirits can be used from Containment Jars, so this mod builds on items from both of those mods.^[1]

Step 1: Make the Sacrificial Altar

The one item from this mod that the pack's recipe data shows is the Sacrificial Altar. It is made at an Ars Nouveau enchanting apparatus, not on a normal crafting table. The pack has changed this recipe, so don't rely on what you may remember from the mod's defaults. Here is the exact in-pack recipe:^[3]

Sacrificial AltarChanged by the pack

Enchanting Apparatus (ars_nouveau)

• Drygmy Token
• Containment Jar
• 2× Sourcestone
• Golden Ritual Bowl
• 4× any silver ingot

Recipe id: ars_ocultas:altar

Crafted at the enchanting apparatus. This is the pack's changed version of the recipe.

Check the ingredients in the block above before you start gathering. The recipe pulls in items from both Ars Nouveau and Occultism, including a Containment Jar, which is the same kind of jar the mod's spirit features use.^[1][3]

Step 2: Get to know jars and spirits

The mod's headline feature is spirits working from Containment Jars. This is what the project page says they do:^[1]

• Spirits automatically pull items around them in a 7x7 area and process them.^[1]
• You can also right-click items on the jar to process them yourself.^[1]
• A jar holding a spirit accepts items from pipes, hoppers and starbuncles.^[1]
• Janitor Spirits try to push their contents into an inventory placed on top of the jar.^[1]

Same as in the All the Mons 0.6.0-beta guide

Ars Ocultas is an integration mod that connects Ars Nouveau and Occultism. The core idea is that spirits from Occultism can work from inside Containment Jars from Ars Nouveau.^[1]

Spirits in Containment Jars

Once a Containment Jar holds a spirit, the spirit automatically pulls items from a 7x7 area around the jar and processes them. You can also right-click items on the jar yourself to have them processed.^[1]

Automation

A jar with a spirit inside has an Item Capability attached, so you can pipe items into it. Pipes, hoppers and starbuncles all work for this.^[1]

Janitor Spirits do something extra. They automatically try to push their contents into an inventory placed on top of the jar.^[1]

Sacrificial Altar

The mod adds the Sacrificial Altar. In this pack it is crafted at the Enchanting Apparatus, and the pack has changed its recipe from the mod's own.^[3][4]

Sacrificial AltarChanged by the pack

Enchanting Apparatus (ars_nouveau)

• Drygmy Token
• Containment Jar
• 2× Sourcestone
• Golden Ritual Bowl
• 4× any silver ingot

Recipe id: ars_ocultas:altar

This is an Enchanting Apparatus recipe, and the pack changed it.

Same as in the All the Mods 10 5.5 guide

In this pack, Ars Ocultas has one pack recipe that makes one of its items: the Sacrificial Altar. That makes the Sacrificial Altar your clear entry point into the mod, so it's the first thing to aim for.^[5]

The Sacrificial Altar

You don't make the Sacrificial Altar at a crafting table. You build it in an Enchanting Apparatus, and this pack has changed its recipe from the mod's default. If you're following an older video or another pack's guide, check the in-pack recipe below before you gather materials.^[5]

Enchanting Apparatus (ars_nouveau)

• Drygmy Token
• Containment Jar
• 2× Sourcestone
• Golden Ritual Bowl
• 4× any silver ingot

Recipe id: ars_ocultas:altar

Crafted in an Enchanting Apparatus. This recipe is changed by the pack.

Unverified The pack sources don't include any quests for Ars Ocultas or any tier structure beyond the Sacrificial Altar, so a full step-by-step progression path can't be confirmed for this pack.

Same as in the All the Mods 10 5.5 guide

Ars Ocultas is a bridge mod: its whole job is connecting Ars Nouveau with Occultism. If you're running both magic mods in this pack, this is what lets their systems work together instead of side by side.^[1]

The Sacrificial Altar

The main in-pack recipe tying the three mods together is the Sacrificial Altar. You craft it in Ars Nouveau's Enchanting Apparatus, and it combines parts from both Ars Nouveau and Occultism, including an Golden Ritual Bowl and a Containment Jar. This pack has changed the recipe, so check the version below rather than an older guide or video.^[5]

Sacrificial AltarChanged by the pack

Enchanting Apparatus (ars_nouveau)

• Drygmy Token
• Containment Jar
• 2× Sourcestone
• Golden Ritual Bowl
• 4× any silver ingot

Recipe id: ars_ocultas:altar

Crafted in the Enchanting Apparatus; changed by the pack.

Unverified The sources don't describe what the Sacrificial Altar does once you've placed it, so test it in-game before you build your setup around it.

Occultism spirits in Containment Jars

The biggest feature is that you can use Occultism spirits from Ars Nouveau's Containment Jar. Instead of letting a spirit wander around, you keep it in a jar and it keeps working.^[1]

• A spirit in a jar automatically pulls in items around it in a 7x7 area and processes them.^[1]
• You can also right-click an item on the jar to have the spirit process it by hand.^[1]
• Jars holding a spirit accept items through automation, so you can feed them with pipes, hoppers or Ars Nouveau's starbuncles.^[1]
• Janitor spirits get a special trick: they automatically try to push what they're carrying into an inventory placed on top of the jar.^[1]

Unverified The mod's project page says the Ars Ocultas section of Ars Nouveau's Worn Notebook has a full overview, but that guide section hasn't been confirmed for this pack.

All the Mods 10: To the Sky 1.8 ships Ars Ocultas 2.2.0. The mod has been in the pack since version 1.0 or earlier.^[6]

Ars Ocultas 2.2.0

• Added support for Crystallizer spirits, so they can automatically transfer items to nearby inventories.^[7]
• Added the Sacrificial Altar, a new block for sacrificing mobs from Mob jars. It consumes 5,000 Source and must be placed under the golden sacrificial bowl.^[7]
• Raised the minimum required versions of Occultism and Neoforge.^[7]

Unverified No pack changelog entries for Ars Ocultas were available, so changes made by the pack itself across its releases are not covered here.
