Maw Fiend

A Maw Fiend heading east

Maw Fiends are Demons. They're a species of Regurgitators.

Regurgitators earn their name with an unusual AI. They will fight melee style, and quite effectively, but their first priority is to waddle around the battlefield, consuming whole the corpses of dead monsters. These they chew up for a moment, before spitting the partially-digested remains at the nearest character or minion. These corpses deal fairly minor physical damage and can be blocked like any other projectile, but they make up in gross what they fail in damage. Corpses so eaten are destroyed, and can not be used by any corpse skills, or resurrected by monster shaman.

One of the most amusing bugs in the history of Diablo II was in the first version after release; at that time Maw Fiends could eat the corpses of dead mercs, and spit them just like any monster corpse. This was a problem since mercs so eaten were bugged, and could not be resurrected in any way, permanently losing all equipment on the merc.

The weakest Maw Fiends in Hell difficulty are found on the Pit of Acheron, while the strongest are found on the River of Flame.

Offense

Maw Fiends eat monster corpses and spit them at players, dealing physical damage.

Type	Melee Attack	Attack Rating	Ranged Attack

Defenses

• Regen Rate tells what % of a monster's hit points are recovered per second. Standard is 1.2/sec.
• Blocking values are assigned to every monster in the game, but the ability is seldom enabled, so most monsters can not block (Hence the blocking % given on most Diablo II monster pages, including Blizzard's, is inaccurate.) When enabled, blocking tells what % of successful, blockable attacks will not damage the monster. Monsters need not carry a shield to block.
• Drain Effectiveness tells what % of a character's mana and life steal apply to that monster. 100 is all, 0 is none.
• Chill Effectiveness tells what % of a character's cold length applies to the monster. 100 is all, 0 is no freeze/chill at all.

Type	Defense	Blocking	Regen Rate	Drain Effectiveness	Chill Effectiveness
River of Flame	151 / 741 / 1568	--	1.2/sec	100 / 85 / 75	50 / 40 / 33
Pit of Acheron	-- / 786 / 1518	--	1.2/sec	-- / 85 / 75	-- / 40 / 33

Resistances

• Resistances over 99% are listed as immunities and monsters will take no damage from that type of attack.
• Immunities can be "broken" by skills that lower resistance, if the value drops below 99%. See the Resistances page for more details.

Type	Physical	Fire	Cold	Lightning	Poison	Magic
River of Flame	0% / 0% / 50%	0% / 0% / 0%	0% / 0% / 0%	0% / 0% / 0%	0% / 0% / 110%	0% / 0% / 0%
