Flesh

The flesh is a boss which appears in the Warrens, after the Swine boss. Like other bosses, it has three variations (Inchoate, Unstable and Formless) and features 4 different parts that change each round and have their own specifics. They all share the same hitpoints, thus, killing one part will end the fight.

Ancestor's Memoirs: The Flesh
"My zeal for blood rituals and summoning rites had begun to ebb, as each attempt invariably brought only failure and disappointment. Progress was halting, and the rapidly accumulating surplus of wasted flesh had become burdensome. I could not store such a prodigious amount of offal, nor could I rid myself of it easily, possessed as it was by unnameable things from outer spheres. When excavations beneath the manor broke through into an ancient network of aqueducts and tunnels, I knew I had found a solution to the problem of disposal. The spasmodically squirming, braying, and snorting half-corpses were heaped each upon the other, until at least I was rid of them. The warrens had become a landfill of snout and hoof, gristle and bone - a mountainous, twitching mass of misshapen flesh, fusing itself together in the darkness."

History
The Ancestor eventually got tired of his attempts at demonic summoning, with his most successful creation being the uselessly stupid and ravenous Swine King. He was left with the problem of a massive amount of demon-possessed pig flesh that couldn't easily be disposed of. The Ancestor found the solution to this problem once his excavations broke into a vast, ancient system of tunnels and aqueducts. He poured the nightmare, shape-shifting flesh into the Warrens, and promptly forgot about it.

Strategy
Have high blight, stun and bleed resist, target the Heart piece whenever it appears. Marking is only effective when used not in the end of the turn, as the piece you've marked may change between turns, same goes for stunning and debuffing. Have a tough front row, as Maws of Life is heavy-hitting. Ranged characters are reccomended, as pieces with high protection may spawn in the front line and reduce the effectiveness of melee characters.

Because the four slots share a single health bar, the Houndmaster ability "Hound's Harry" is particularly effective against this boss, especially when combined with the dog treat. If all bleeds land, the effectiveness of the damage over time is essentially quadrupled. Use of Hound's Harry can trivialize the fight, taking down the health of the boss extremely quicky. Similarly useful is the Plague Doctor's "Plague Bomb" as a multi-target DoT.
