Valley of the Rogue Magi  

This is a special instance that is targeted at solo players or up to a group of 3. The Potion of Earthwalking to enter the zone is sold by Merchant Marcus. If you die inside you can purchase another potion to enter.

The humanoids and gargoyles do not respawn but the elementals and undead do.

When the Perennial Abbot and Champion are killed there is a chance that Arch Magus Naerius will spawn (or his placeholder).

Magus Geofry Marus is another triggered rare, who is triggered (or his placeholder) when you climb to the top of the tower.

This zone has a 90 minute lockout.
