Iron

Iron is used to build most Buildings and Units. It is particularly valuable to Attackers who use Droids instead of Soldiers, as droids require iron to build whereas soldiers do not.

Iron is produced by Mining Facilities. Like other Resources, it can also be acquired on the The Galactic Market and/or received as Aid from your Family.

Iron is susceptible to the Destroy Iron Spell so, like Gold, guard it well.

0.5% of the Iron in your stockpile will Decay each Turn. The only way to offset this decay is to sell your surplus each turn on the market. Do note that Iron that doesn't get sold in the same turn will suffer the 0.5% decay rate on the market as well.
