Undead Jailer

Unofficially named Mummified Hollows are enemies in Dark Souls II..

Location
Introduced in the "Cursed" trailer, they linger in a large unnamed castle-like structure.

Description
Large, mummified enemies adorned in capes and wielding large glaive-like weapons.

Strategy
These enemies move slow, but can inflict heavy damage up close and at a distance, due to the length of their weapons.

Due to length advantage, it's probably most effective to engage with long range sorcery or up close melee.

They also appear to have a grab attack, where they grab the player by their necks, hold them above their head, and then slam them into the ground.
