Strategy 1 (Melee)
The first phase: The best opening is when he slowly vomits lava from your left to right. Just run next to his left leg (your right) and attack a few times before he is done. The next best opening is when he lowers his club to his left side and slowly swings it to his right side. Again move towards his left leg without target lock and dodge the swing behind him. Do not attack yet because he is about to continue with a AoE blast. Keep moving towards the tip of his tail and when you catch it you are far enough to avoid the AoE and take a few swings at the tail. A weapon with a lot of range and wide swipes is recommend.
Staying too long near him and especially in front of him triggers the fast AoE mouth blast. Attacking only a couple of times and then retreating to medium range to wait for openings is easier.
In the second phase: Now Old Demon King has a certain attack pattern: 1-2 melee attacks/combos and then a ranged attack. Usually no two ranged attacks in a row. Same openings as in the first phase works here too but triggering them is different. You can out range every long range attack of this boss. As you return to medium range to catch his melee attack openings do not stop approaching. Keep moving towards him until he does a melee attack. If he lowers his club for the slow swipe do the same thing as in phase one. If it is any other melee attack you can dodge or even walk under him to get behind him.
Strategy 2 (Toxic)
Dodge its attacks until you get into range and cast Toxic Mist. Once the boss is poisoned, stay as far away as you can so it can't hit you with its spells. When the toxic wears off, get close and reapply it. Four rounds of toxic should do it.
The Storyteller's Staff's weapon art is also very effective and a single cast will nearly defeat the boss by itself. One or two attacks will be enough for the poison to finish him off without having to reapply it.
Strategy 3 (Bow)
The Old Demon King can be easily defeated using a bow if you have a shield with good fire damage mitigation like the Dragon Crest Shield. Other than his fire spray attack, which you should block, there is nothing he can do to you if you keep your distance.
He moves slowly enough that it's possible to simply shoot him whenever he stops to perform an attack and continue to run away without him ever getting a chance to hit you; at some point in the fight, he'll start moving a bit faster, but it's still not fast enough to run you down.
It also helps to take advantage of one of the two mounds of corpses in the arena. Circle around one walking backwards, keeping your distance, and dodging the lava spew, lava AoE, and meteor attacks. Combined with the Cloranthy Ring, the Grass Crest Shield, and lots of careful rolling, this boss becomes almost trivial.
Strategy 4 (Pyromancy)
This fight will either be near impossible or very easy depending on how far you've advanced your pyromancies. The boss is extremely resistant to fire spells, so your best bet instead is to attack him with non-fire pyromancies. Boulder Heave will work, but your very best bet is getting access to Karla's Dark Pyromancies.
Using Black Fire Orb will make this an easy fight. Stay at range and evade his melee attacks, which have relatively limited range. During Phase II, the only attack you have to worry about is his expanding fire circle. You can either move out of range, or roll through it at the right time to dodge the damage. Whenever he casts a spell, he leaves himself open to several Black Fire Orbs. When he summons the meteor shower, simply run until the meteors explode. Around 20% hp the boss will collapse and explode. As long as you outrange this explosion, the fight is essentially over, since the Old Demon King will simply lay there and not attack anymore.
|Swing||The demon will swing his hammer, causing fire and melee damage, beware AOE, move under the attack, toward the weapon, or get behind or below him|
|The demon will conjure a circle of fire that will move inwards or outwards from him, can be blocked.|
|The demon bashes his hammer in the ground, starts turn it around in circles|
|The demon bashes his hammer in the ground, linear trails of fire covering different directions will emit from the center. Take Evasive Action.|
|A phase two move, multiple slow flaming rocks will fall towards the player. Slight tracking. If you are quick, hit and run works. Evasive action and use of pillars to absorb shots is effective.|
|The demon will spew lava at those infront of him. He will move his head to extend his AOE. His range is short and those flanking him or under him can smack him.|
- The Old Demon King is the oldest and last remaining demon of the city of Izalith, as it is the last remaining witness of the chaos of said city. "The shriveled Old Demon King is now like a clump of burnt ash, but he is the last living witness of the Chaos of Izalith." - Soul of the Old Demon King.
- "This weapon has survived since old Izalith, and is imbued with remnants of the Chaos Flame." - Old King's Great Hammer.
- If, when entered the arena, you go straight forward and then, look carefully up on the left side on top of the pile of dead demons that are surrounding the whole area, you can see the Centipede Demon body; reference to Dark Souls.
- During the second phase of the fight, if the player listens carefully to the song playing, they can hear a small slightly remixed excerpt of the Bed Of Chaos's theme.
