Guild Wars 2

Does the “Vengeful” trait (increases retaliation by 20%) work with “Stand Your Ground” on other allies? Or does it only count with retaliation gained in other ways?

I just tested it on my own. For future reference with anyone else wondering, the answer is yes. I recommend that the tool-tip be revised whenever the appropriate trait is equipped (Just like the recharge rate of skills is properly changed when certain traits are used).
