After reaching this rank, you should obtain four individual weapon parts: Enduring Legacy Polymer Syncytium Blueprint, Enduring Legacy Synthetic Fiber Blueprint, Enduring Legacy Nano Tube Blueprint, and Enduring Legacy Blueprint.
As always, you will need to craft three materials using resources and an item of the Amorphous Material. Each individual component will take two hours to research, and the weapon itself will take four hours. You will also need 250,000 gold for all the research.
