Dungeons and Dragons Online will be getting its last big patch of the year, Update 24: Heart of Madness. Considering the cheery title, one might expect scarring challenges and experiences that will drive your average player insane (including using yourself as a puzzle piece to get through a fiendish game).
The crux of the patch centers around an invasion from the plane of madness to Eberron, with popular D&D figures like the Lord of Eyes, the Lord of Stone, and Yalthoon the Mindflayer. Players will tackle a trio of high-level madness-themed dungeons in this paid adventure pack, although there will also be a fourth free dungeon that's part of the ongoing Wizards of the Coast Tyranny of Dragons event.
Update 24 will also come with cosmetic armor effects, smarter AI monster champions, and a revamp of Barbarian enhancements.
