I ran Honor of the waves explorable with a group the other day that did this. Unfortunately I was a little tipsy when we ran it, and it didn’t really occur to me that it was an ‘unintentional feature’ until all was said and done. It also helps that someone clearly indicated at that point that it was a bug. Once again, hindsight is always 20/20.
Apparently after the zealot fight, it’s possible to skip an entire path and go straight to the plunderer fight. There’s a tunnel/alcove in path 3 leading to the area where Wollam the Plunderer is, and after a certain amount of time has passed (several minutes) it’s possible to clip through the divider in place (or it might flat out disappear, I honestly forget) and go right to the end of path 2. I wouldn’t be able to tell you precisely where, for reasons stated above. However, I’m pretty sure that it was somewhere in the main chamber, and I’m sure that you could find it without much effort. If it helps at all, we did path 1 first without any issues.
Our group consisted of a charr necro, a human guardian, a sylvari ranger (myself), and I have no recollection of what else.
I searched the forums just now and couldn’t find any mention of this. I don’t really have any idea how well known this is, but I figured you guys would probably want to get right on this one considering that for every lone person in a group who knows about it, 4 more are about to find out. And of course, it goes without saying that I have no intention of repeating this, as I like not being banned.
