What are your cheesy strategies for the formless flesh? Here is mine (that I borrowed from you guys)

[Mr. G]

After failing the Brigand 16 Pounder so many times I needed a break. This seemed like a champion boss I could beat.

I used:
Vestal-Hound Master-Jester-Leper.

My plan was to stack bleed with the jester and houndmaster (using hounds harry to get four bleeds going at once and the jester 2x bleed AOE attack). I also just hammer hew with the Leper as this boss has a shared hp pool.

What cheese builds or strategies do you guys enjoy on this one?

It's good that you're using Hound's Harry for this boss, although next time I would pair the Houndmaster with a trinket that increases the chance to inflict bleed, preferably the "Spiked Collar". Bleeding chance increases as well as damage. This is just to prevent the possibility of the Formless Flesh randomly resisting bleeding attacks. Then again, I would just bring in 4 Houndmasters with that trinket (and a dodge trinket) to spam Hound's Harry. They have a good enough health pool and the ability to guard and heal themselves, so theoretically it would be the quickest and easiest fight.
