Gelum (Cold)
Gelum, the aspect of cold, is a base Thaumcraft 4 compound made from Ignis and Perditio. One point costs 2 primal points to synthesize from scratch.
Recipe
Combine one point of each component at the research table to get one point of Gelum. Counting all the way down to primals, a single point takes 2 primal points:
That total is the number the solver shows as craft cost when it places Gelum in an empty cell. It is cheap enough that Cheapest routes use it freely.
What Gelum connects to
Gelum links to 2 aspects in this library (see the connection rule): its two components.
| Neighbor | Why it connects | Craft cost |
|---|---|---|
| Ignis | Component of Gelum | 1 |
| Perditio | Component of Gelum | 1 |
No compound in this library is built from Gelum, so its only neighbors are its own components. A fixed Gelum on a note has to be approached through Ignis or Perditio.
When Gelum is printed on your note and you only need to leave it, Ignis is the cheapest first step at cost 1.
Reaching Gelum from each primal
These are the shortest valid chains in this dataset, using base Thaumcraft 4 aspects only. Where several chains tie on length, the one with the cheapest in-between aspects is listed. Cost counts only the aspects between the two ends, the cells you would have to fill.
| From | Chain | Cells to fill | Cost |
|---|---|---|---|
| Aer | Aer → Lux → Ignis → Gelum | 2 | 3 |
| Terra | Terra → Victus → Mortuus → Perditio → Gelum | 3 | 6 |
| Ignis | Ignis → Gelum | 0 | 0 |
| Aqua | Aqua → Venenum → Perditio → Gelum | 2 | 3 |
| Ordo | Ordo → Permutatio → Perditio → Gelum | 2 | 3 |
| Perditio | Perditio → Gelum | 0 | 0 |
A real note also has geometry: the chain has to fit the free hexes between your endpoints. If the gap is longer than the chain, pad it by stepping back and forth between two aspects that connect, or let the solver find a layout that fits.
Data source
Gelum is in the base Thaumcraft 4 group. Its default commonness is 68 out of 100, an editable estimate used by the Common ranking. The component pair was compared with Azanor's Thaumcraft API, Minecraft 1.7.10 branch. The recipe table covers every component pair and the version limits.
