For a Level 85 Second Age LI you need:
- A Tarnished Symbol of Celebrimbor: You can get this from Skirm camp for Marks+Meds, from AH for Gold or from Level 85 Raids/Warbands for Time (lootboxes and other random stuff may also yield one, but that's far less reliable)
- A Crest of Rohan: Again you can get this from Skirm camp, AH or from Warbands, but the most common source are crafting nodes (you need to be at Eastemet level with a gathering profession for that)
- A max guilded Eastemet crafter of the relevant profession (e.g. woodworker for staff)
- The other materials (wood/iron, fragments) are pretty cheap to get and usually provided by the crafter
If you want to get things from skirmish camp you can get marks+meds mostly from scaled group instances. Solo skirmishes and Warbands are an option too, but will take a while.
