Rare Resources

Summary
Rare resources are much less common than the normal types, but are very useful. There are several ways to obtain rare resources: There are seven types of rare resources, each of which has its own uses:
 * 1) Opening chests
 * 2) Defeating Elders
 * 3) Crafting with Dust
 * 4) Through Guild chest rewards
 * 5) Occasionally breaking a block will yield one rare resource
 * 6) Cages (requires watching an ad)
 * Red Beryl
 * Anaptanium
 * Trillium
 * Moonstone
 * Arcanite
 * Saronite
 * Thorium

Uses
Rare resources are mostly used in building, upgrading buildings and mines, and crafting quest items.

Anaptanium

 * Trading post
 * 1 - Level 11
 * 5 - Level 51
 * 9 - Level 91
 * Total: 15
 * Solar Plant
 * 1 - Level 5
 * 2 - Level 12
 * 3 - Level 19
 * 3 - Level 24
 * Total: 9
 * Chemistry
 * 20 - Level 5
 * Fauna Module
 * 20 - Level 2
 * 10 - Level 3
 * Total: 30
 * Ocean Maker
 * 10 - Level 2
 * Bot Upgrade
 * 5(40) - Claiming Oi11

To complete every upgrade currently in the game, you will need a total of 124 Anaptanium. However, as there is no benefit at all to having multiple drones that can claim oil, you should not need more than 89. This makes Anaptanium the least-needed rare in the game, and the one that lends itself most readily to being turned into Dust (see below).

Arcanite

 * Trading post
 * 4 - Level 41
 * 8 - Level 81
 * Total: 12
 * Solar Plant
 * 1 - Level 4
 * 2 - Level 11
 * 3 - Level 18
 * 3 - Level 23
 * 4 - Level 30
 * Total: 13
 * Bot Upgrade
 * 2(16) - Boost Smelting
 * 20(160) - Directly Mine a Resource
 * Chemistry
 * 40 - Level 6
 * Ozonizer Module
 * 10' - Level 3

To complete every upgrade currently in the game, you will need a total of 251 Arcanite.

Moonstone

 * Greenhouse
 * 4 - Level 1
 * 10 - Level 2
 * 20 - Level 3
 * 40 - Level 4
 * Total: 74
 * Solar Plant
 * 1 - Level 10
 * 2 - Level 17
 * 4 - Level 25
 * Total: 7
 * Rocket Type B (a crafted item)
 * 2600 - 1 per Rocket

To complete every upgrade currently in the game, you will need a total of 81 Moonstone, but if you want to visit all 2600 Class B asteroids, you will need another 2600 Moonstone, so 2681 total. You can continue consuming Moonstone to make Rockets after that (e.g. if you want to supply them to a fellow member of your guild), so there is no upper limit on the amount of Moonstone you can use.

Red Beryl
To complete every upgrade currently in the game, you will need a total of 130 Red Beryl; if you want to visit all 2600 Class C asteroids, that will bring the total to 2730. You can continue consuming Red Beryl to make Rockets after that (e.g. if you want to supply them to a fellow member of your guild), so there is no upper limit on the amount of Red Beryl you can use. There is no benefit to multiple drones being able to claim water, so you can save 35 Red Beryl by never teaching more than 1 drone this ability.

Dust
At any time the player can trade their rare resources for dust, which can be used to create other rare resources. The exchange rate is one resource for one dust, but six dust for one resource. This means that you should only trade resources for dust if you are in dire need of a resource, or if you have too much of the less useful resources.
