Lord of the Rings Online has just unleashed update 5, the Armies of Isengard. Five is the magic number, after all. Yes, there are more quests, yes, there’s Saruman making himself a Ring, yes, ogres and trolls and whatnot. The real takeaway here is a brand new musical instrument, which seems custom designed to shatter eardrums and annoy all. Should be a hit. Ten Ton Hammer has the story.
