Harbor Chain
Ever needed to secure your waterways, but walls just don't cut it? Just use Harbor Chains! Build two towers, and lift the chains up and down as you please!
How to use
- Build a chain tower on each side of the water, ring side facing each other, 6 to 45 m apart (30 m if either tower is wooden).
- Stone chain tower (stonecutter): 20 stone, 10 wood, 1 chain, 2 iron.
- Wooden chain tower (workbench): 12 core wood, 10 wood, 1 chain, 2 iron.
- While you place the second tower, a green line shows the link, or a red line with the reason it won't link.
- Press E on either tower to raise the net from the seabed or lower it again.
- Raised, it stops ships and swimmers. Lowered, ships sail over it.
