Guild Wars 2

So far I have 3 of them and just need the one in blue. Is there a timer or do I just wait for it to get to level 3 defenses and pact control?

No those are randomly spawn for each VW runs, so pay attention to map chat, often people will call out when a legendary spawns and what camp it spawns in. I think for every player its different luck, because my last on was Amber and that one i had to go through soo many runs to get the one, but over all they spawn randomly out of blue from what im feeling. So just do SW as it is and keep and eye out for legendary spawn call. So good luck man, hope you get that “The Tormentor” Title. ^.^

Thanks, so far it has been luck of being in the right place at the right time.

Blue is a little harder to spot because it shows up southeast of the fort rather than joining the assault. Possibly a good thing, it would massacre everyone in close quarters.
