Guild Wars 2

I know the way to stack aura’s by changing weapon set (draw legendary-swap-change weapon-effect from legendary mode-on) but i have to keep this legendary on my 2nd weapon set. Today while doing charr fractal i saw something strange. I was changing weap sets when i figured i have juggernaut effect on me (my legendary btw) without having it equipped. Gs on main and LB on alternative, yet still shiny.

I was trying to make the same thing outside that specific fractal but didnt work. any help ? suggestion ? Stacking with ascalonian mage or watchwork tonic doesnt work on juggernaut.

Did you enter or exit water? Also have you tried the toxic krait tonic?
