The Mergo's Chief Attendant is an enemy in Bloodborne. They are a unique type of enemy, and only three can be found in the game. They are found around the Nightmare of Mensis area; inside the castle's archives from Mergo's Loft: Base lamp, and in Mergo's Loft: Middle. They wield a giant cleaver in the right hand and a chain in the left, and will use both weapons to attack.
Mergo's Chief Attendants aren't noticeably more difficult than other heavy enemies. One must be aware that she can call in help from nearby Mergo's Attendants and that her attacks build up Rapid Poisoning.
These enemies have no variations, and the only existing type in the game are equipped with cleaver and chain. One guards a shortcut elevator, together with two crossbow attendants, and another will patrol the section after the curved double staircase.
A third chief attendant can be found in the area where the Micolash fight takes place, at the bottom of the spiral staircase where a Moon rune (or Madman's Knowledge) can be found.
- Parrying her while she brings the cleaver down is the most effective way to dispose of this enemy. This attack has a large parry window and is very slow.
- Heavy weapons stagger her easily. You may have to dodge first as her chain strike is fast.
- Attacks include: a vertical cleaver chop, a two-handed guillotine attack, a chain whip attack and slashes.
- They are known to drop Dirty Blood Gemstone, the source of Rapid Poison Blood Gem.
