Mobility upgrade
Improved Fins Guide
Improved Fins upgrade everyday swimming mobility. Conduit Crystal puts this craft beyond the opening Lifepod material loop; combine it with an Alien Ruins supply trip once deeper travel is comfortable.
Quick answer: Craft Improved Fins at the Fabricator with 1 Basic Fins, 1 Fiber Mesh and 2 Conduit Crystal after unlocking the blueprint. The existing Basic Fins are consumed as an ingredient, so bring them to the craft.
