The Old Dragonslayer can be found in the Cathedral of Blue (2880 HP). He is opposite to the Dragonrider and is accessible after raising the lever to lower the drawbridge. The Old Dragonslayer's moveset is nearly identical to Dragon Slayer Ornstein's with the exception of dark magic attacks.
Masterless Glencour can be summoned from a ledge just to the right of the Dragonrider's arena. A fearless tank knight wielding a greatsword and a shield, Glencour will immediately rush the Old Dragonslayer after stepping through the fog gate, and continue to distract and inflict moderate damage throughout the battle, making him an invaluble ally to those having trouble conquering the Old Dragonslayer in a one-on-one situation.
The fight is very similar to the Dragonslayer Ornstein and Executioner Smough battle without Executioner Smough. There are slight differences in how the Old Dragonslayer fights compared to Dragonslayer Ornstein. An example would be that the Old Dragonslayer uses a dark magic attack, while Dragonslayer Ornstein did not. Otherwise, Old Dragonslayer has the same sort of movement and similar attack patterns as Dragonslayer Ornstein in the original Dark Souls should the player slay Executioner Smough first. If one takes his time fighting with him, he will shoot three dark magic orbs to the player from the tip of his spear
Blocking until the Dragonslayer misses an attack may prove to be beneficial to the player, as well as backing away when he begins to cast his magic attack. Using a bow or crossbow may result in being able to stun lock him by shooting him in the head. The Old Dragonslayer is weak to magic and is also vulnerable to lightning-based attacks.
One highly effective strategy is strafing counterclockwise (player's right), as most of his attacks come from his right, making it especially hard to hit the player. It is possible to not have to block using this.
Charge: While the player has some distance between him, he will kneel down and charge at the player lunging his spear towards the player.
Jump strike: Leaps into the air and slashes his spear on the ground
2 hit Combo: Swings his spear horizontally twice in a row
Lunging Uppercut: Lunges his spear forward and afterwards proceeds to perform an uppercut
Impale: Grips his spear with 2 hands and lunges it at the player. Unblockable, if the attack connects the player will be impaled lifted up in the air and thrown back down. This attack is simialr to Ornstein electricity impale move in Dark Souls. Has a defence boost for a few seconds during the attack.
Dark Bonzai: His body will emit dark aura, then he will proceed to jump into the air and land on the ground exploding in a dark AoE attack. Very similar to Ornstein's bonzai move except this one explodes in dark and not electricity.
Dark Barrage: The Spear glows in a dark aura and lunges it, and doing so will fire off several dark bolts at the player
