Unenchanted Elven greatswords will begin to appear throughout Skyrim at level 19 and enchanted greatswords can be found at level 20. These locations include:
- Blacksmiths and general goods merchants.
- Wielded by various characters or enemies.
- Found as random loot in chests or as a world item.
- One may be found in Folgunthur, just before the Dragon-door. There is an off-shoot to the right of the path leading to the door that is submerged. It is difficult to see because the water is not deep enough to fully submerge in, but the greatsword is just under the surface. (Must be of the appropriate level for the sword to be there.)
It can be upgraded with a Refined Moonstone ingot at a grindstone. The Elven Smithing perk doubles the improvement.
