Purchase the Focused Sight skill from the Resilience tree. Next, find a group of enemies that includes one melee enemy and clear out the rest. Then, hold
to use Focused Sight which will dodge melee attacks. When your force energy is depleted, move/dodge attacks until you have one bar of force energy and repeat the process. All 50 attacks needed for this trophy can be earned on a single target in 5-10 minutes.
