Pirate Quelling Quest

From AEWiki

You can start this quest by talking to Renzel in Varg. Renzel, who has a grudge against Scalo, asks you to kill 40 of Scalo's Pirates. (Pirate Captains and Pirate Scallywags do not count.)

Pirates can be found in Scalo's Hideout, directly south of Varg. After you have killed 40 Pirates, talk to Renzel and you will be awarded 5,000 epool.

The second part of your reward will require you to search a chest on the 3rd level of Krythan Crypt, which can be found Northeast of Varg near the coast. In the chest you will find the object of this quest, a Coronation Tunic.
