If you're below level 82, I'd recommend doing three rockbreaker instead of three arm of the destroyer for trash pulls. rockbreaker is 130 potency for all enemies where arm of the destroyer is 110, but once you get the upgrade to shadow of the destroyer, then use that. It's still 110 potency, but like bootshine it's got a gaurenteed critical hit, which means that you'll get 3 charkras getting you most of an enlightenment to follow up your blitz.

Basically it's 3 of any of the same form move gets you elixir field, so you can mix it up if you need to, like a twin snakes and two true strikes if you realize once you activated it that your damage buff was about to fall off, or as mentioned above dragon kick + bootshines.
