For anyone who has not found how to get their third Pyrite Doubloon (yarrrrr) in Rift, here is how to get it Defiant style!

The Quest is called: Trouble on the Route
Questgiver: Stratego Iakale (just inside the main gates, by the horses)

To complete the quest, run down to the road and talk to the troublemaker. He will immediately spawn two moderately powerful enemies. Kill them and return to Stratego Iakale to get Doubloon 3 YARRRRR!
