Guild Wars 2 – Assist Dianna by Undermining Bandit Salvage

“Defeat bandits, destroy bandit turrets and food supplies, and set off mining explosives.”

Head to the North of the Shadowheart Waypoint or to the Southeast from the Overlord's Greatcamp Waypoint. Past the split in the road you will find Seraph Soldier Dianna. Head over to her and talk to learn more of what is happening in this area:
Seraph Soldier Dianna: “We have proof that bandits are directly working with the centaurs. So far they've only been helping move centaur supplies, but who knows what they'll be doing next?”
Hero A) “How can I help stop them?”
Dianna A) “We've got to slow the bandit's salvage operation down. If you can destroy their supplies, cull their numbers, or set off any of their explosives before they're ready, it should help.”

Hero B) “Why would humans back the centaurs?”
Dianna B) “The bandits may be human, but they could care less about the safety of Divinity's Reach. The weaker the Seraph and Queen are, the less to interfere with bandit operations.”

This one is a lot more simple. Start with the bandits wandering the outside of the camp. As you thin their numbers you will clear your own way into their salvage camp to the East of Dianna. It will not take too long just killing bandits to complete the quest.

If you want to do other things, wait for some of the events to trigger to open up a few more options. One of the most obvious will be the cannons. Aside from them, head into the lake and approach the camp from the West. This will give you access to their explosives which can be a lot of fun just to trigger and wreck some havoc.

When you complete the renown quest you will get the letter, “The Bandits are Wilting” with 1 silver, 28 copper:
“Thanks for assisting at Mudbay Digs. We've been able to slow the bandit's support of the centaurs, diminishing the threat they pose to Fort Salma. Without your help, the battle may have already been lost.

“Thanks again – Dianna, Seraph Soldier”
