Tool · Common
Mirifuir Key is a siege-progression tool item obtained exclusively from the Mirifuir Siege event. To farm it, participate in the siege and engage the high-ranking Sinecure officers that spawn during the event chain — these elites are the listed drop source in community catalogs. The key grants access to locked doors inside Fort Mirifuir, so it is a one-time progression item rather than a repeatable farm. If you did not get the drop on your first siege completion, re-run the Mirifuir Siege when it cycles back (approximately 3-hour cooldown) and defeat the Sinecure officers again. There is no merchant source for this key.
