Progression 19: The Drúadan Forest

It's time for part 19 of the Progression Series, The Drúadan Forest! Last time, I hunted down and destroyed not one, but TWO champions of the underworld cabal plotting against Denethor. For more information on that see here: (https://ringsdb.com/fellowship/view/12110/progression18thestewardsfear)

This time, I will be attempting to beat The Drúadan Forest while also completing a challenge for the quest. To see the full rules for my progression series see the first fellowship here: https://ringsdb.com/fellowship/view/11104/progression1thecoreset.

Today's challenge:

Ominous Drumming: Drúadan Drummer enemies cannot be optionally engaged

Please feel free to leave any comment or challenge suggestion for the next pack, as I aid the townsfolk of Anórien in Encounter at Amon Dín!
