Anyone else having issues with Soundless for the Undersea Usurper part of this achievement? I, personally, have this achievement completed but there are several people who have brought to my attention that they have been trying to get Soundless for several months without success. I believe this rare has been an issue for years since the zone resets depending on people in the zone. Would be nice to have an adjustment made to this rare so people can complete this achievement, if in fact it is still an issue.
One option.
Park a character of appropriate level range at Soundless spawn area in both Warmode On, and another character in Warmode Off.
If you cycle those characters every 20-30 minutes over any given day. However long you can check. You may be surprised how often its up.
If one character finds the spawn up. You want to keep farming on both warmodes. Bring a 3rd alt. 4th. 5th. However lucky you get.
