Position on map I have done both from the sides(first run through) and mid(last 2). Mid is definitely easier & less chance of dying. Only problem is the boomers can shoot swordbearer while hitting crota. But, as for swordbearer I stand on "coffin" in front of his door and kill him as soon as he comes out. I use super to go invisible and as soon as I'm invisible, team fires rockets as I jump up from front. 3 or 4 RTs depending on timing. Drop sword and blink strike crota to invisible. Rockets out, another 3-4 RTs and either go to rock on left or back to coffin, depending on position. Then back in for a third down, rockets out & as many hits until sword disappears. If done right he will be at the O in crota or near it after first cycle. He'll move to the right, stay alive until he moves to middle again, and repeat process
