Forbidden and Arcanus: The Clibano and Rune Crafting

guide

The Clibano combustion furnace is Forbidden and Arcanus's material engine, and runes are its magical currency. This guide covers both.

Clibano combustion

The Clibano runs combustion recipes that go beyond a vanilla furnace. It smelts ores into ingots (copper, gold, iron), produces Arcane Crystal and Arcane Crystal Dust, and makes advanced materials like Obsidiansteel Ingot, Netherite Scrap and Rune. It is faster and more capable than a normal furnace, so it becomes your main smelting block.

Runes

Rune is made by smelting or blasting Runic Stone, and runes are the components behind the mod's magical devices and rituals. Keeping a stock of runes lets you build the mod's altars and enchanting-style gear.

Residues and blocks

The Clibano's processing leaves residues that the combine residues recipe reforms into useful blocks — the Arcane Crystal Block, metal storage blocks, Deorum Nugget and Rune Block — so little is wasted. Between the Clibano, runes and residue recovery, Forbidden and Arcanus turns ordinary mining into a steady supply of magical materials.

The Clibano is fifteen recipes on both versions

Clibano Combustion carries exactly 15 recipes on 1.21.1 and 1.20.1 alike — one of the few categories in this mod that did not change between builds. That makes it a safe thing to plan around whichever version you run.

What did change is large

The two builds differ substantially elsewhere:

Crafting — 144 recipes on 1.21.1 against 172 on 1.20.1
Stonecutting — 14 against 39
Combine Residues — 0 on 1.21.1, 10 on 1.20.1
Smithing Transform — 1 on 1.21.1, none on 1.20.1

So the older build actually carries more recipes overall, and the residue-combining system is exclusive to it.

Modifiers

Apply Modifier holds 6 recipes on 1.21.1 and 5 on 1.20.1 — a small system, but the one that upgrades gear.

Scale

228 pages across 120 items and 108 blocks, with no structures at all, so everything here is crafted rather than found.

Why the residue system matters on the older build

Combine Residues exists only on 1.20.1, where it carries 10 recipes. Residues are by-products, and a system for recombining them means the older build recovers material that the newer one simply does not produce a use for. On 1.20.1 it is worth keeping residues rather than discarding them.
