Obtainability

These special metals can be obtained in various ways:

• Mining iron ore
  When mining iron ore on planets there is a very small chance that an additional metal will drop. Although this might be the easiest way to obtain these metals, it's most definitely the least profitable.

• Dungeons
  Armoured troops in dungeons have a chance of dropping metals. This is the fastest way to obtain metals, but also the hardest, as most dungeons with armoured troops are very hard to survive in. For more information about which specific metals certain dungeon mobs can drop, check out the dungeons page.

• Crates
  Opening crates is another way to obtain metals. Planetary crates have a chance of dropping the metals tied to the planet, and non-planetary crates (rare, legendary) have a chance of dropping metals which aren't tied to planets. Metal Crates only drop metals, but the chance of obtaining the right metal you want is quite slim, as all metals are droppable in that crate.

• Quests
  A few quests have metals as a reward, but these are simply bonus rewards and aren't recommended as a consistent income of metals.
