Standing Stone Games is trying out a new type of instance for these festivals, starting with the two that arrive in today’s Update 22.3. These include “The Perfect Picnic” with all sorts of cool rewards (want a raincloud pet?) and a revamped boss fight against Thrâng. The rest of the summer festival offerings will also be available, so head over to the LOTRO Wiki for a full guide through these.
Update 22.3 also makes significant changes to the Hunter’s Lingering Wound skill, adds a search bar to the quest log, and puts a throttle on global chat message frequency to combat spamming.
The game worlds have reopened. Thank you! #LOTRO
