Galien

Behaviour and Tactics
Galien has three main attacks: Having the Shade Cloak is recommended here, as it can be tough to react to the smaller scythes while dodging the main scythe. Otherwise, Galien has no teleport, and is slow and large enough that it is easy to stay underneath him and continually attack him.
 * Scythe Spin: Commands a scythe that spins rapidly and bounces off the floor, slowly tracking The Knight. He will occasionally command it to return to him before sending it off again.
 * Scythe Ricochet: Once damaged enough, commands the scythe to bounce around the room, not tracking the Knight.
 * Soul Scythes: Once damaged enough, spawns first one, and then two smaller spinning scythes which will also ricochet off the walls as the large scythe continues to move.

Abyss Shriek/Howling Wraiths is also effective.

To the left of Galien's corpse is a short path that leads to a Lifeblood Cocoon. This is advantageous to use as it lets the player take a few more hits that could result from losing focus on the smaller scythes.

It is advised to kill Galien quickly, as his scythes can become overwhelming if they are left for a long period of time.

Trivia

 * Judging from its jagged edge and grey colouring, Galien's scythe appears to be a larger version of a Mantis Traitor claw. Whether it is actually a claw or was simply made to resemble one is unknown.
 * Due to a bug, hatchlings from the Glowing Womb charm do not target Galien.
