Great VictoriesG 10

The fastest/easiest way my partners and I got this was re-rolling all of our current quest objectives until each one was for the Ascended Tower trials, then we made sure they were for killing enemies or bosses level 70+. Some of them had kill it with fire or weapon techniques which is all good, but we did this twice and got our achievements. To find level 70+ enemies you will need to reach at least tower level 11.
