The main item (the item to be infused) rests on the central pedestal. The components being infused into the item rest on the pedestals surrounding the central pedestal. The Infusion Altar will also draw Essentia, the amount and type varying per recipe.


  1. First, the Infusion Altar will consume the Essentia needed to make the item.
  2. Then, the Infusion Altar will consume the items needed to make the item.
  3. Then, the item will be created.

Thaumcraft 5 has various "instabilities"- when an infusion recipe is unstable, various things can go wrong- items will ejected, lightning will come out of the Runix Matrix and may strike the player, and warp may be given. Here are all of the instabilities, from least unstable to most unstable-

  1. Negligible
  2. Minor
  3. Moderate
  4. High
  5. Very High
  6. Dangerous

Decreasing instability

Instability can be decreased a number of ways-

  • By making the pedestals symmetrical- spreading them around the altar rather then making them cluttered together.
  • By putting various blocks around the Infusion Altar. This includes Tallow Candles and skulls.

The symmetry that the Thaumcraft altar uses is: Each stabilization item must, at the same Y level, have a corresponding item on the other side of a line that goes through the runic matrix.

Very important is that every unpaired stabilization item adds 10x more unstability than is removed by a paired item - so a very small number of unbalanced items can totally destabilize an altar.

Altar Ranges

  • Stabilization items can be 10 below to 5 above the runic matrix, and in a 25x25 area around the matrix.
  • Jars must be in the stabilization item area.
  • Pedestals must be in the 17x10x17 box that is below the runic matrix.


Thaumonomicon entry

Arcane crafting and alchemy can go only so far. Something better is needed to create truly powerful mystical objects.
Infusion crafting is the process of infusing a single object with magical energy and the properties of other objects. You could, for example, infuse a stone with Aer vis and a feather and it would result in a very light stone.
As is usual with thaumaturgy, things are not quite that simple. To even get started with infusion crafting there are several things you need: A Runic Matrix, arcane pedestals and a ready supply of magic in the form of essentia.
Once you have your Runic Matrix properly placed into a structure commonly known as an Infusion Altar, you can begin to craft.
The central pedestal located under the matrix is where the item you wish to infuse will go. You will also need several more pedestals placed around the altar where you can place the blocks and items you wish to infuse into the target object. Lastly you will need warded jars or similar essentia containers holding the requisite amount of vis.
Once all this is gathered you can click on the Runic Matrix with a wand to start the crafting process.
During the first stage of crafting essentia will be drained from nearby sources. Crafting will stall if there is insufficient essentia available - something that you do not want as will be explained on following pages.
Once all the required essentia has been infused into the target object, the other objects will have their essential essence drained. Only when this is done will the crafting process complete.

Infusion crafting is not without risks. The entire process involves forcing vast energies into a single object. Unpredictable things tend to happen.
Usually one of the fusion objects get knocked off a pedestal, or flux gets generated, but more catastrophic events are not unheard of.
The longer crafting continues due to unresolved problems like lack of vis or dropped items, the greater the chance of something bad happening.
These effects can be reduced by various means. Firstly you wish to keep the entire fusion structure as symmetrical as possible - take careful note of where you place pedestals and make sure they are balanced with other pedestals on the opposite side of the altar. When placing fusion items into them you may wish to keep them balanced as well. Lastly you can place occult paraphernalia around the altar in symmetrical formations (things like candles, skulls, crystals, etc.). These will have the effect of reducing instability.
Ancient Stone
The strange, ancient stone you have found has some interesting mystical properties. You believe that when used to craft the pillars for an infusion altar that it will help reduce the amount of essentia required during infusion crafting and speed up the crafting process by a small amount. It will however increase instability slightly.
Should you find pedestals crafted from the same material each one will also help reduce essentia costs.
Eldritch Stone
The dark, eldritch stone you have discovered has some strange properties. When used to craft the infusion altar pillars it will help reduce instability and speed up the crafting process by a moderate amount. It will unfortunately increase crafting cost slightly.
Should you happen accross any pedestals made from the same material it will have much the same effect. Caution should be taken to carefully balance them however as unbalanced eldritch pedestals will massively increase your instability.
