You either have to ignore it, waiting for the melee shield to drop or you kill the Gilded Mystic at the start and you can then say keywords to Darta (on the stairs at zone in) to deal with various things that happen, as follows:
Melee Shield: Keikolin
Suffering: Silverwing
Pests (Thralls): Harla Dar
Manipulator: Venesh
All too much trouble, imo. Also, killing the Gilded Mystic opens the "window" and you have more chance of being thrown out.
I did it when I first started, leaving my bard by Darta and telling him to give Darta the relevant keyword when stuff happened. The idea is that the named dragon comes in and removes the issue (melee shield, pests, etc.). I now find it simpler to just kill stuff.
In short, either go through all of that or just ignore it and it will drop.
