Fusion Altar

Fusion Altar

The Fusion Altar is a multi-block structure (added by EFV2Addon) that allows players to combine two enchant books into a more powerful one. Some enchantments — like Vampire Lord and Excavator Master — can only be obtained through fusion.

Rename notice: EFV2Addon was previously released as "CustomEnchantsV2". The base plugin it depends on is now called EnchantsForge (formerly CustomEnchants).

Build Structure

The Fusion Altar uses a different structure than the EnchantsForge Enchanting Altar. It is built on a single Y level with a Lodestone at the center.

Top-Down Layout

        [CryingObsidian]
               ↑
[CryingObsidian] [🕯Candle][Lodestone][🕯Candle] [CryingObsidian]
               ↓
        [CryingObsidian]

Full layout (5×5 footprint, same Y level):

  [ ]   [ ]  [CObs]  [ ]   [ ]
  [ ]  [Cnd] [ ]   [Cnd]  [ ]
[CObs] [ ]  [LODE] [ ]  [CObs]
  [ ]  [Cnd] [ ]   [Cnd]  [ ]
  [ ]   [ ]  [CObs]  [ ]   [ ]

Legend: - [LODE] = Lodestone (center) - [CObs] = Crying Obsidian (±2 blocks N/S/E/W) - [Cnd] = Lit Candle (±1 block diagonals)

Required Blocks

Block Quantity Position
Lodestone 1 Center (0, 0, 0)
Crying Obsidian 4 N/S/E/W at ±2 blocks, same Y
Candles (Lit) 4 NE/NW/SE/SW at ±1 block diagonal, same Y

Lighting the Candles

The candles must be lit for the altar to be recognized. Place the candles, then use Flint & Steel to light each one:

1. Place all 4 candles at diagonal positions
2. Right-click each candle with Flint & Steel to ignite it
3. All 4 must be lit simultaneously

Warning: If any candle gets extinguished (rain, water, etc.), the altar will stop functioning until it is re-lit.

Note: Candle color does not matter — any color candle works.

How to Use the Fusion GUI

Step 1 — Interact with the Lodestone

Right-click the Lodestone (center block) to open the Fusion GUI.

Step 2 — Place Your Enchant Books

The GUI has designated slots for: - Input Slot 1 — First enchant book (e.g., Lifesteal III) - Input Slot 2 — Second enchant book (e.g., Vampiric II) - Protection Slot — Optional failure-protection item

Step 3 — Check the Recipe

The GUI will show: - The output enchant (if the combination matches a fusion recipe) - The XP cost - The success rate (e.g., 60%) - Whether a failure-protection item is applicable

Step 4 — Confirm the Fusion

Click the Confirm button to attempt the fusion. The result depends on the success rate:

Outcome What Happens
Success You receive the output enchant book
Failure (no protection) Both input books are consumed, nothing gained
Failure (with protection) Protection item is consumed, input books are returned

Step 5 — Retrieve Your Book

If successful, take the output enchant book from the GUI's output slot.

Failure Protection

Fusion has a configurable success rate (default 60% for most recipes). To protect against failure:

  1. Place a failure-protection item in the dedicated protection slot
  2. If the fusion fails, your input books are returned (the protection item is consumed)
  3. If the fusion succeeds, the protection item is returned unused

Tip: The default recipe uses NETHERITE_SCRAP as the failure-protection item. This can be changed in fusion.yml.

XP Costs

Each fusion recipe has its own XP cost defined in fusion.yml. The default recipes cost 30 XP levels each.

Troubleshooting

Problem Solution
Right-clicking Lodestone opens vanilla Lodestone UI Ensure the full structure is built correctly
GUI shows "Invalid recipe" The two books don't match any fusion recipe
Candle getting extinguished Build an overhang to protect from rain
Structure recognized incorrectly Ensure Crying Obsidian is used (not regular Obsidian)
