Why iron is a major progression gate
Iron unlocks a large jump in combat, tools and building options. The challenge is not understanding the recipe; it is surviving the Swamp long enough to extract meaningful quantities.
Prepare before entering the Swamp
- Bring poison resistance and good food.
- Set a portal in a safer nearby location, not inside a risky combat path.
- Carry a hoe or terrain tools if water and movement become a problem.
- Leave valuable backup gear at home.
Crypt runs
Sunken Crypts are a key early source of scrap iron. Clear methodically, create safe retreat points and avoid overloading yourself so badly that one fight turns into a failed recovery run.
Moving iron efficiently
Metal transport forces logistics decisions. Use boats and staging bases rather than trying to solve every trip with one overloaded character.
