What I like to do is start the fight out while in sword oath, and stay that way until after the outer purple lanes appears just before the second repel. Then I swap to shield oath, pop tempered will to prevent knock back, circle of scorn on left add immediately, run over and flash the right, then when both are near me I hit flash 3-4 more times and am set to go back to dpsing the wall if doing burn strat or if not, helping out kill the bees while still dodging lanes and moving for repel of course. Also helpful tip is to focus target the demon wall so you can still watch for repel if you're fighting the bees. Also worthy to note is that you can actually stop both bees AOE move if you're quick; Shield bash one, switch targets, Spirits Within.
