This will probably work best if you can lock down a freeplay session with a full party, sometimes randoms can come along and end the event. Difficulty probably effects the amount of enemies, this was on GM1. STEPS: 1. Go to freeplay and find an Outlaw event, there's at least one other place this event can spawn, it's near Academy Ruins 2. Kill enemies until the boss spawns, make sure not to kill the boss 3. Fly away from the event until the quest icon disappears from your HUD 4. Go back and keep killing, rinse and repeat. P.S. Please excuse the NA aim and mouse cursor in the middle of the screen.
