Channeler

Channelers are enemies in Dark Souls.

Locations
In the Undead Parish just before the Bell Gargoyles (Does not respawn).

In The Depths above the Gaping Dragon boss room (Does not respawn). This Channeler will buff the Gaping Dragon if he is not eliminated first, making the boss fight considerably harder.

There are three in the Duke's Archives. The first is located after the first elevator just up the stairs. The next two are close to each other above the bonfire on the balcony. All three respawn.

Description
Channelers are six-eyed sorcerers who serve Seath the Scaleless. They wield long Channeler's Tridents and cast Soul Arrow to attack players from afar. The Channelers in the Duke's Archives will teleport when they take damage. Their armor set, Channeler's Set, can be found in the Duke's Archives in a chest.

They perform a unique martial arts dance that stirs nearby allies into a bloodthirsty frenzy.
