Break the Blockade
+250 Valiance Expedition
Take Petrov's Cluster Bombs and drop them on enough pirates to kill or destroy 25 Blockade Pirates and 10 Blockade Cannons. Once you've accomplished that, return to Bombardier Petrov at Westguard Keep.
All of our ships are sunk! We need your help to break the pirate blockade below in the Shattered Straits!
If you can't bomb them to smithereens, I'm afraid we'll never be able to break the blockade.
We're talking again are we? That must mean that you've done it! You've shown those rotten Northsea pirates a thing or two!
That's what I wanted to hear! You've got the stuff, <name>, that's for sure!
You think maybe you could come back again tomorrow when we've made more cluster bombs?
I wonder what's taking him so long?
Prior to Patch 3.3.3, a player with flying ability could land on one of the crossbars of a ship and bomb the pirates from there. A quick pattern could be established and the quest completed within a couple minutes, as opposed to waiting for the zeppelin to plod along its course. This may have been fixed in a patch prior to 3.3.3, but was only first noted afterwards.
