Third boss is very similar. Mt stands @ the front corner of that room by the metal gate. He should get the first 3 before the boss. If there are 3 big squares on the ground if you stand close to

side between the square by the boss and the next one that first group of mobs will spawn there. You just flash and run straight ahead to the next group and grab that w/ flash op and the

others will funnel towards the group and you just pick them up. Just rotate you hate rotation w along w/ flash now and then and you should be fine.

The way I do it might not be exactly how a lot of people do it but, I have yet to hear any complaints.
