Lord of the Rings Online servers will be patched today to bring Update 23.1 on board that includes the Harvestmath Festival, as well as a number of bug fixes, class updates and more. In addition, the Grey Mountains instances are back in service with drop rates "increased significantly for both favored and standard chest openings on tier 2 difficulties".
The Curse of the Eerie Acres reaches its conclusion: speak to Bingo by the Party Tree to begin the new quest chain (and replay last year's quests if you would like to get caught up on the story). The enterprising hobbit Begonia Grubb is starting a new Harvestmath Festival tradition called Treats or Trickery! Look for her near the Haunted Burrow, in a housing neighborhood, or at the new festival location of Wistmead to learn more. There are also six additional quests to enjoy in Wistmead, as well as a new wheat maze and other activities! As always, new rewards are available, including a Black Cat pet, a new dress, a new Festival Mount, and more!
Harvestmath runs from October 17th through November 7th and includes a Wheat Maze and some new quests along with old favorites like the Shire & Bree-land Horse Races, Troves & Trickery and Pumpkin Patch Picking. Players can earn a number of tokens that can be traded for all kinds of in-game goodies. Check out this guide for more.
