"Epic Undertaking is achieved by cleansing 15 corpses within the span of 5 seconds while fighting Deathlord Bjarfrud Skjoralmor in Veteran Falkreath Hold."

Attempted this achievement today, witha few strats, but wondered if anyone has done this and what strat they found best?

So far best strat seems to keep a few of the archers adds alive till boss is lower health, then nuke adds once a bunch spawn in?

Any tips or other reccomendations would be appreciated.
