Per Patch 1.62:
- Free the Rogue - we have made some significant changes to this quest to make it easier for players to lure Mercal from his hiding place. Also, players no longer need to accompany Mercal on his return to town, he will meet you there.
Talk to Arden, the instrument merchant in Caer Diogel, and he will send you to rescue Mercal who is hiding near Krondon (Ogre Citadel). You must have good Ogre faction or bring some friends to help out.
For Mercal to appear, the Ogre in the keep must be alive. If you kill the
ogres you will have to wait for them all to respawn or else Mercal will not
appear, since upon appearing they automatically die. So if you are having
problems with getting Mercal appear, just wait a bit. According to the CSR I spoke with, Mercal is scared of the ogres, and won't pop if there are ogres around his hiding place, so you may have to kill them before trying to get him to pop.
Once you have gotten there, there are three barrels, and if Mercal is not there, speak his name and he will spawn (the three barrels you're looking for are just to your left when you exit the main Krondon entrance. When you get close to them you get a message stating "You have entered a shadowy corner." Then say "Mercal" and he should show up. The precice location of this is Aldland 26670,5172,3660).
He will thank you and then take off towards Caer Diogel, follow him. Talk to Mercal and he will give you some documents to give to Arden who will then reward you.
