So this is our third straight week of repeat bosses from June. I do have a couple of new tricks up my sleeve that I didn't have last time I fought these guys, though.
The Heimdall strat utilizes the bug in 3.2 where you launch Pledge's ultimate, switch to LE and then quickly pause the game. VP's ultimate will stop raining dmg until she returns, in which case her ultimate will pick up where it left off, in the same spot. So as you fight the boss, you have to lead him back to the starting point before you finish him.
I ended up using VP's charge attack a hair too soon, but Judah saved me. The bug apparently is getting fixed in 3.3, so this is probably our last chance to use it.
