Guild Wars 2 – Help Sesto Headsplitter with his Work

“Test out Sesto headsplitter's experiemental weapons and help keep the experiments at Irondock operational.”

head over to the Eastern bank of the Irondock. There, in the practice yard, you will find Sesto Headsplitter who will explain everything about what is going on in Irondock.

Head around the island itself where they are doing the work. You will find Iron Legion engineers who are laying about. Help them up and you will earn some progress. In addition, look around the area. There you will find malfunctioning machinery. This will be just about any machine that you can interact with in this area. Just head into it and interact. This will repair it enough that it will be functional again.

Take some time and explore the area. Talk with the various charr around. Some of them will ask you to help out with an experiement. Each of them has a chance, at least, to explode in your face. The rest of the time it will work. Either way you will make progress for your efforts.

When the renown quest is complete you will get the letter, “The Iron Legion Thansk You” with 79 copper:
“(Hero's Name),

“I wanted to let you know how invaluable your help at Irondock proved to be. Thanks to you, we were able to continue our work on the experimental weaponry we are testing there. Without you, there is no doubt that this program would have suffered a tremendous setback. I believe that the new equiment and machinery that is being tested at Irondock will eventually be the secret to finally vanquishing all the legion's foes. And when that day comes, your name will be included among the list of brave soldiers who made such a victory possible – Sesto Headsplitter”
