Iron mine is a technology structure used to unlock Kingdom structures requiring the iron technology (or Iron Age). It's found in the forest of the fourth island.
Activating[]
The iron mine is locked and cannot be activated until the Monarch activates the stone mine.[1] The activation does not require gems, but only coins. Once paid twenty coins, the mine is "self-repaired" without the help of builders, and gives access to:
- the forge
- higher tiers of towers, walls, and the town center.
Campaign[]
Without this tech, the Kingdom structures can only reach the stone tier. After paying for this tech in the fourth island, the Monarch is allowed to upgrade them to the iron tier on any island, even if the Monarch loses the Crown.
Challenge Islands[]
The iron mine is present on Dire Island and on Plague Island. It cannot be found on Skull Island, where the iron technology is available from the beginning.
Advanced logging camp[]
In Norse Lands, instead of iron, the second technological tier is the advanced woodworking, unlocked at a more complex logging camp found on the fifth island. The structures upgraded with this technique have a denser appearance, being composed with robust, well cut and juxtaposed planks.
