Ah, greatswords. Perhaps the most commonly used two-handed weapon in LOTRO. Many of the these skins share similar appearances with one-handed swords commonly dropped by creatures in pre-Moria zones and instances. I've never been an avid collector of this weapon type, but I do occasionally go out of my way to collect specially named ones, like Hill-defender and Warrior's Pride, both of which are listed here. The best thing about greatswords? Most of the landscape drops share crafted skins. As a result, I'll share only the crafted recipes to prevent (hopefully) hours of grinding.
Like previous collection entries, this isn't the full set of greatsword appearances. Only what I've collected over the years and where I've found them. There about thirty of them featured here. I didn't have enough to start a second entry--as I list twenty per--so they'll all be found here.
(Minor update here -- I've actually found a few more since I wrote this post. Now there are thirty six listed here, enough for two entries. However, I don't have the time to rearrange my posting schedule again. This will be image heavy!)
And just in case someone notices this, some of these are called "great swords" as opposed to "greatswords." Somewhere over the years, the crafting/item developers shifted from two words to one, but never changed the old item names to reflect the change. Make sure you use the appropriate spelling when hunting down the correct skin for your own collections.
