Featured Instance Rotation

The Featured Instance rotation follows a six-week roster. The weekly instance changes on Monday at 10:00 a.m. server time, and the quests reset daily at 3:00 a.m. server time. On Monday it is possible to do the daily quests twice without using Mithril Coin to reset them: once after the daily reset time but before weekly rotation time, and again after the instance changes.

The list of instances in the rotation have changed several times after the introduction of featured instances, with U18.2, U19, U19.1.1, U20, U21, U22, U22.2, U23.0, U32.0, 34.3 and U38.
