the last "Ask the Dev Team" session with the Lord of the Rings Online developers, we knew that some changes were coming to the game's Legendary Weapon system. The latest Developer Diary entry is devoted entirely to filling in some of the details on these changes, which should come into effect when the Siege of Mirkwood expansion launches in December. First and foremost (and definitely one of the best tweaks) is that you'll be able to tell if a legendary weapon will ever turn into something good before you pour time and money into improving it.
There will also be a brand new item type, a series of "legendary item advancement scrolls". They will provide an alternative method of improving or altering legendary weapons, and will be found both as loot from enemies and from the deconstruction process. In addition, crafters are getting a significant nod with the introduction of a fourth relic slot that can only be filled by player-crafted relics. It gets better: every crafting profession can make a different kind of relic, providing a range of improvement options, and ensuring that no crafter is left out of the fun.
