Arcanum Mod for Minecraft: Complete Tutorial & Spotlight

The Arcanum mod is a content-rich Minecraft mod that introduces a progression system built around powerful new ores, game-changing armor sets, devastating weapons, and even a handful of unique food items. Whether you’re playing solo or in a large modpack, this guide walks you through everything Arcanum adds — from your first green sapphire to an infernal chestplate with 999 toughness.

New Ores Added by the Arcanum Mod

Once you load a world with Arcanum installed, you’ll begin finding six new ore types generating underground. These are:

Green Sapphire Ore

Blood Diamond Ore

Void Diamond Ore

Vanilla Random Ore — randomly generates vanilla ores

Mod Random Ore — randomly generates modded ores

Bone Ore, Flesh Ore, and Sulphur Ore — used to craft bones, rotten flesh, and gunpowder respectively

The three core progression ores — green sapphire, blood diamond, and void diamond — are each progressively rarer than the last. Void diamond in particular spawns at only one per chunk, making it extremely scarce in standard survival play. In modpacks featuring large quarries or automated mining, however, gathering them becomes significantly more manageable. The rarity is intentional, since the gear crafted from these ores is extraordinarily powerful.

Arcanum Armor Progression

Arcanum’s armor system is built around a tiered upgrade path. Each tier requires the previous tier’s piece plus new materials, creating a satisfying and challenging progression. Below is the full breakdown using the chestplate as the reference piece.

Green Sapphire Armor

The entry-level Arcanum armor is crafted purely from green sapphires. The chestplate provides 8 armor and 20 toughness — already competitive with late-game vanilla options.

Blood Diamond Armor

The blood diamond chestplate steps up significantly, offering 10 armor, 40 toughness, and 3 knockback resistance. To craft it, you’ll upgrade a diamond chestplate using netherite quartz and blood diamonds.

Void Diamond Armor

Upgrading the blood diamond chestplate with void diamonds yields the void diamond chestplate: 16 armor, 60 toughness, and 5 knockback resistance. Be prepared — you’ll need quite a few void diamonds for this upgrade.

Infernal Diamond Armor

To reach this tier, you first need to craft infernal diamonds. These require blocks of void diamond, blood diamonds, and a blaze rod. Use the infernal diamonds to upgrade your void diamond chestplate into the infernal diamond chestplate: 50 armor, 80 toughness, and 10 knockback resistance.

Infernal Chestplate (Final Tier)

The ultimate armor piece in Arcanum. Using 4 more infernal diamonds, you upgrade the infernal diamond chestplate into the Infernal Chestplate, which boasts a staggering 999 armor, 999 toughness, and 100 knockback resistance.

Hidden Enchantments on the Full Infernal Set

The full infernal armor set doesn’t list its bonuses as traditional enchantments — they are built directly into the items. Wearing the complete set grants all of the following effects:

No hunger drain

Automatic health regeneration

Super jump (Jump Boost 7)

Extreme speed (Speed 7)

Creative flight

Depth Strider

Feather Falling

These bonuses make the full infernal set one of the most powerful armor sets available in any Minecraft mod. The Speed 7 and Jump Boost 7 effects alone make traversal almost unrecognizable compared to vanilla gameplay.

Arcanum Weapons

Just like the armor, Arcanum’s weapons follow a tiered upgrade path — each one dramatically more powerful than the last.

Beating Sticks

The earliest Arcanum weapons are the beating sticks. Despite their humble name, they come with built-in Smite, Sharpness, and Bane of Arthropods — baked directly into the item rather than shown as visible enchantments.

Sword Progression

The sword tiers and their attack damage values are as follows:

Green Sapphire Sword — 12 attack damage, 4 attack speed

Blood Diamond Sword — 52 attack damage, 4 attack speed (upgraded from a diamond sword)

Void Diamond Sword — 77 attack damage

Infernal Diamond Sword — 102 attack damage

Infernal Sword — 10,002 attack damage

Other Tools

Arcanum also includes hoes, pickaxes, shovels, and shears at equivalent tiers. These tools come with dramatically increased durability and built-in bonuses — for example, Looting on swords and Fortune on pickaxes — making them extremely overpowered compared to their vanilla counterparts.

Food Items Added by Arcanum

Arcanum doesn’t stop at combat gear — it also adds several unique food and drink items with impressive saturation values.

Crushed Apple & Crushed Apple Toast

Using a crafting hammer, you can crush an apple to create a crushed apple. Combine that with two sticks and bread to craft crushed apple toast, which provides 100 saturation and 5 hunger.

Drinks & Beverages

Arcanum adds a small selection of craftable and findable drinks:

Caught Wine — found in the world; can be enchanted with Unbreaking

Unfermented Beer — crafted with an uncraftable potion, a red cup, and wheat

Beer — brewed from unfermented beer

Apple Cider and Warm Apple Cider — crafted by smelting the base cider

Mountain Dew — crafted from a mountain dew mix; provides 20 saturation

Summary: Is the Arcanum Mod Worth It?

The Arcanum mod offers a complete and deeply rewarding progression system for players who want gear that goes well beyond vanilla Minecraft’s limits. Yes, the infernal set and weapons are wildly overpowered — but the extreme rarity of void diamonds and the multi-step upgrade chain means you’ll earn every piece you craft. The experience will vary greatly depending on your modpack: in a quarry-heavy pack the grind shortens considerably, while in a vanilla-adjacent world it becomes a true long-term goal. Add in the food items for a bit of variety, and Arcanum is a well-rounded mod well worth adding to your game.
