Collecting materials on Terragrid

Terragrid is a unique region on New Terra that contains more than 45 different biomes divided into 400 unique lands. Each of these lands contains several materials that can be discovered by units placed on the region.

Arperta region's map.

Each environment (e.g. Volcano) generally contains at least 5 different materials. However, some regions may contain more or less than 5 materials. The land plots belonging to the same region (e.g., Large Forest J1, J2, J3, K1, K2, K3, etc.) all contain the same materials. It is up to each player to strategically position their units on the map to discover as many materials as possible.

When mining materials on Aperta, a few rules apply:

• Common active units cannot discover materials.

• To discover materials, an Active must be rare or above.

• A unit can discover materials with a rarity between common and its own rarity. For instance, legendary units can discover common, rare, epic, and legendary materials while rare units can only discover common and rare materials.

• Since units cannot discover a material bearing a rarity above its own, only ultimate units can discover ultimate materials.

• The rarer the unit, the higher the probability it has to discover a material.

• Extractors mine three times per hour on the cell they are placed on

• Common Constructions can discover materials

• Constructions simultaneously mine on 7 cells (Active units only mine on 1 cell at a time)

• The probability of discovering a material per hour follows the following table:

	C	R	E	L	U 1-4	U5
Proba. / hr (ACTIVE)	0%	0.25%	0.42%	0.67%	1.17%	1.33%
Proba. / hr (EXTRACTORS)	0%	0.25%	0.42%	0.67%	1.17%	1.33%
Proba. / hr (CONSTRUCTION)	0.17%	0.25%	0.42%	0.67%	1.17%	1.33%

Note: Those values are multiplied by 1.4 if the Apertian Station is powered using energy cells.

• If a unit discovers a material, the rarity of the material is determined as follows (applies for both Actives and Constructions):

	Com. Mat.	Rare Mat.	Epic Mat.	Leg. Mat	Ulti. Mat
Common unit (applies only for constructions)	100%
Rare unit	70%	30%
Epic unit	45%	35%	20%
Legendary unit	20%	20%	40%	20%
Ultimate unit level 1-4	5%	10%	41%	41%	3%
Ultimate unit level 5	2.5%	2.5%	30%	60%	5%

Therefore, for material discovery/harvesting, the NFTM of an NFT on the grid is not taken into account. Any material gathered on Aperta is considered as Discovered.
