Terra (Earth)
Terra, the aspect of earth, is one of the six primal aspects. It has no recipe, costs 1 in the solver, and is a direct component of 7 compounds.
Recipe
Terra is primal: it cannot be made by combining other aspects at the research table. Primal points come from scanning blocks, items, and creatures with the Thaumometer. Because every compound is built from primals, Terra appears somewhere in the recipe tree of 42 of the 68 other aspects in this library.
What Terra connects to
Terra links to 7 aspects in this library (see the connection rule): the compounds that use it.
| Neighbor | Why it connects | Craft cost |
|---|---|---|
| Victus | Victus = Aqua + Terra | 2 |
| Vitreus | Vitreus = Terra + Ordo | 2 |
| Herba | Herba = Victus + Terra | 3 |
| Iter | Iter = Motus + Terra | 3 |
| Metallum | Metallum = Terra + Vitreus | 3 |
| Perfodio | Perfodio = Humanus + Terra | 11 |
| Tutamen | Tutamen = Instrumentum + Terra | 12 |
When Terra is printed on your note and you only need to leave it, Victus is the cheapest first step at cost 2.
Reaching Terra from the other primals
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 → Motus → Iter → Terra | 2 | 5 |
| Ignis | Ignis → Potentia → Ordo → Vitreus → Terra | 3 | 5 |
| Aqua | Aqua → Victus → Terra | 1 | 2 |
| Ordo | Ordo → Vitreus → Terra | 1 | 2 |
| Perditio | Perditio → Mortuus → Victus → Terra | 2 | 5 |
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
Terra is in the base Thaumcraft 4 group. Its default commonness is 100 out of 100, an editable estimate used by the Common ranking. The primal declaration was compared with Azanor's Thaumcraft API, Minecraft 1.7.10 branch. The recipe table covers every component pair and the version limits.
