Tools of the Mistrade  

This quest is given by Quint Cerlius M.E. after you complete Manifest Destiny.

You must kill 8 Deathfist Runesmiths in Zek. These can be found near the Druid Ring. The Runesmiths share a spawn with the escorts.

After completing this task you should return to Quint Cerlius M.E. for your choice of rewards, and to open up the Reports from the Borderland quest.
