I’ve given up.
This boss is just UNbeatable on heroic.
I’ve had constructed decks that were OP af where i thought nothing could ever beat me and then this piece of sht boss comes around and kills me at round 5.
I only managed once to get him “killed” but then he just got replaced by other rats.
Tried the sewers so many times now and this boss always showed up as 6th or 7th encounter.
The 1/10 spam paired with cheap buff spells is just unstoppable.
Either you try to clear his board which will never work because the rats are just too tanky or you try to rush his hero down which will never work at least at 7th encounter because he’ll have 5 completely buffed up 6/16 rats at turn 5 that crush you.
Good design 10/10 not trying this sewer crap on heroic again
