Mohg, the Lord of Blood, is one of Elden Ring’s toughest bosses. Elden Ring throws you a bone by making Mohg an optional boss but for us completionists, optional still means mandatory. So we have to kill him, and this boss guide is going to help.
This boss guide is not going to tell you where to get the best Elden Ring armour or weapons to beat Mohg. If you want, you can summon a Mimic Tear (or preferred replacement), slap on Radahn’s armour set, grind up a billion levels and make short work of him. Instead, I want to concentrate on Mohg. What attacks of his are most powerful, and how to counter them. Mohg has a rather versatile moveset, so I’ll break down the moments when it’s safest to strike. But before you start fighting him, let’s do some prep.
Elden Ring Mohg Boss Guide Prep
There are two items worth getting. One of them is almost completely integral to survival, and the other just makes his first phase easier. The Purifying Crystal Tear and Mohg’s Shackle.
Purifying Crystal Tear
The Purifying Crystal Tear is for your Flask of Wondrous Physick and is a must-have. Without it, you’re destined to fail. To get the Purifying Crystal Tear, you have to go to the Second Church of Marika in Altus Plateau.
Here, you will fight an invader called Eleonora, Violet Bloody Finger. She is not a very difficult warrior but watch out for her dragon attacks. Make sure you equip the Purifying Crystal Tear to your Flask of Wondrous Physick before you fight Mohg or you’ll regret it.
This item isn’t necessary but it’s bloody helpful. With it, you can stun Mohg and get a bunch of damage in. To find it, you must gain access to the Subterranean Shunning-Grounds in Leyndell, Royal Capital. Before defeating Maliketh, the entrance is rather hidden. But once you have beaten Maliketh, the entrance is right next to where you spawn.
Once inside the Subterranean Shunning-Grounds, you’ll find a labyrinth that reaches deep underground. To make it easy, I’ve made a video to show exactly where you need to go from the first Site of Grace to find Mohg’s Shackle. Beware the giant lobsters.
If you want to practice on an easier Mohg, you can fight his fell omen version at the bottom of the Subterranean Shunning-Grounds.
Infected with the Omen curse from birth, Mohg and his twin Morgott were imprisoned by their mother, Marika. After the shattering of the Elden Ring, Mohg escaped deep underground to his Mohgwyn Palace and took on the title of Lord of Blood. To accentuate his title, the entire vicinity is saturated in blood. Red rivers and pools decorate the cliffs. The fastest way to get to Mohgwyn Palace is by following White Mask Varré’s questline. Otherwise, you can take a portal in the Consecrated Snowfield. You do have to find the hidden passage to the Haligtree which has you fighting Commander Niall, the most annoying boss in the game. So just go with Varré.
Mohgwyn palace is a pretty high-level area so there are a few good treasures around, also it has the best rune farming spot in the game by the Palace Approach Ledge-Road Site of Grace. The best thing to find, though, is the boss fight itself. Climbing to the top of his mausoleum, past the Dynasty Mausoleum Midpoint Site of Grace, you’re invited to one of the most fun boss fights in Elden Ring.
Elden Ring: Mohg, Lord of Blood Boss Guide – First Phase
Mohg primarily has two forms of attack, swinging his trident at you or hucking his blood at you. Let’s start with the blood attacks, as he will usually start off with those.
Elden Ring: Mohg Boss Guide – First Phase Attacks.
During exile, Mohg made contact with a god that imbued his blood with fire. So as his blood stains the arena, it leaves a lingering flame that causes damage when you stand on it. It’s similar to Fire Giant and Rykard. Bloodboon has him reaching into a void above his head. He pulls out a handful of fiery blood and tosses it at you. It comes in three forms. He’ll either throw it in a wide arc or a straight line, leaving a trail of blood between you and Mohg. He will also make it rain down around him so you can’t get close.
If hit with the blood, it will cause you to be afflicted with blood loss. So it pays to have some Stanching Boluses on hand.
For the most part, Bloodboon is relatively easy to dodge. It’s always obvious when he does it by the void appearing above his head. You just have to watch your footing afterwards. There is also a great counterattack—I learned from a player called Ongbal on YouTube—and that’s using the Ash of War Carian Retaliation.
Carian Retaliation can be bought from Seluvis. He’s at the top of Liurnia by Ranni’s Rise.
Carian Retaliation can be attached to any common shield. It’s a shield parry that negates Mohg’s blood and makes three magic swords that chase him. This is perfect for when he uses the shower variant of Bloodboon. It gives you time to get a few hits in afterwards. My tactic is to set the shield with Carian Retaliation to the second right-hand weapon slot. I quickly switch out my main weapon for it whenever I see him reach into the void.
He doesn’t just throw his blood at your though, he’ll also try to blow you up with it.
With his Bloodflame Talons attacks, he tears a fiery void in space which causes his blood to explode. There are two variations, a quick horizontal swipe and a longer thrusting swipe.
He tends to pull the horizontal swipe out quite often, sometimes even mixing it into a combo. After the swipe, a delayed explosion occurs. It might take a few tries to get the timing right, but all you have to do is dodge a second after you see the fiery claw marks. The actual swipe doesn’t do any damage so just try to concentrate on the explosion.
The thrusting version has a much longer build-up so it’s easy to anticipate. It’s quite hard to get the timing of thrust down though because it’s quite delayed, but the explosion comes instantly after the thrusting of his claws. Because the attack has a long wind-up, you may be tempted to try to punish it but don’t because he follows up with a sweeping strike with his trident. The sweeping attack is punishable though, so dodge through it and give him a smack.
Mohg’s Trident Swings
Mohg has a number of different melee attacks he does with his trident. He tends to build them into either two or three-hit combos, also sometimes with an added ground stab attack. Because it’s hard to tell what he’s going to do, it’s not worth it trying to punish his combos at first. After a while, you will get a sense of when to attack because he tends to move away from you slightly after each combo. There are two attacks that are always safe to punish, his ground stab and his thrust attack. Both have long recovery periods so you can get in a few hits as long as you dodge them. With the ground stab, watch out when he pulls it out because it can damage you.
The final of his trident attacks are his Ritual Countdown attacks. He stabs the trident into a void above his head, a big red trident symbol appears in front of him, and then he swipes it out in a forward arc. He does this attack three times during the fight as you knock down his health bar, all in preparation for his Bloodboon Ritual (more on that later). These countdown attacks are great opportunities to get in some damage. When you see him stab the trident into the void, move to his left side or his back and go to town on him. The trident doesn’t track to you, so you’re completely safe as long as you’re not in front of him or to his right.
First Phase Strategy
Now that you know when to attack, what should you hit him with? Mohg is weak to bleed damage so it’s worth it to modify your weapon with hemorrhage effects. He also has surprisingly low poise for a late-game boss so you can use big weapons and heavy attacks to stagger him quite easily.
If you want to use Mohg’s Shackle, now is the only time where it will work for it has no effect in phase two. Mohg’s Shackle can be used twice to bind him to the ground and let you get a bunch of hits in. If you do high enough damage, you could even get him all the way into phase two before he’s able to get any attacks in.
Considering he’s a late-game boss, you should be at a rather high level. He’s easier than the likes of Maliketh, the Black Blade, Godfrey, the First Elden Lord/Hoarah Loux or Malenia, Blade of Miquella, but significantly harder than Morgott, Astel or even the Elden Beast. If you’re as far as Farum Azula, you’re good enough for this fight.
Once you’ve done enough damage—and he’s done his third and final countdown—Mohg performs his Bloodboon Ritual. Phase two begins.
Elden Ring: Mohg, Lord of Blood Boss Guide – Second Phase
Most bosses in Elden Ring signify their phase change with a cutscene, but Mohg is too cool for that. Instead, he saturates the arena with a haze of blood and drains all of your health to heal himself. This is why you need the Purifying Crystal Tear. You can just heal yourself with Crimson Tears as he’s doing the ritual, but then he’ll have a full health bar in phase two and you’ll be down a bunch of potions. Wait until he does his third Ritual Countdown attack (you’ll see three red rings around your character) then drink your Flask of Wondrous Physick. He’ll then go directly into his Bloodboon Ritual, and you get to wail on him the whole time.
A few things change in phase two. His attacks all spray blood on the ground, so it doesn’t take long for the entire arena to become lava. All of his attacks now contribute to blood loss, so keep knocking back those Boluses. Oh, and he can fly. Yeah, he straight up sprouts wings. It’s good fun.
Elden Ring: Mohg Boss Guide – Second Phase Attacks.
Most of Mohg’s attacks stay pretty much the same except now he will sometimes fly into the air, spray blood everywhere, and then launch at you with his spear. I found the best method of dealing with this was to stay back as he throws the blood down then dodge away as he launches at you. It has a really fast recovery time so don’t try to punish it.
A few notable changes to his moveset are the two punishable attacks I mentioned earlier, the thrust and the ground stab. In phase two, the ground stab now follows up with an explosion similar to his Bloodflame Talon attacks. Instead of attaching it to a combo, he’ll either quickly stab the ground or swipe up into the air and slam his trident down. So it’s easier to react to it, but harder to punish. When he jumps into the air, he does one flap with his wings before coming down. So time your dodge right and get behind him for an attack.
He’ll still do his normal thrust attack but now he’ll sometimes twist it, spreading blood everywhere and causing blood loss. Make sure to dodge to the side and you can go in for a back attack.
Second Phase Strategy
This is where you’ll truly be tested. Not only do his attacks cause blood loss and leave fire everywhere, but he also gets much more aggressive. Use Stanching Boluses to prevent Mohg’s blood loss, and be wary of your footing. I found it’s better to try to keep close to him and dodge through all of his attacks. If you keep him localised, all of his blood flames will go over your head. You won’t have to worry as much about standing in it. If you need to heal, wait for him to use his Airborne Assault where you can get some distance from him. Try to keep away from the stairs as it makes it harder to judge your position.
Hopefully, you’ll have a better understanding of his combo attacks so you know when to strike. You can also punish his ground stabs and thrust attacks as long as you’re behind him. Watch for any time he jumps into the air, most of his jump attacks are easily punishable.
After you defeat him, you get Mohg’s Great Rune, the Remembrance of the Blood Lord and 420k of runes. That’s great and all, but the best reward is the knowledge that you can beat the better Omen King. If you’re struggling, that’s a good thing. Every death is an opportunity to learn and get better. Keep calm and concentrate. Learn his moves. Feel your reaction times growing stronger with each dodge, and congratulate your skill instead of dreading your failures. You’re not failing when you die, you’re developing. With help from this boss guide, you can beat Mohg, and everything else in Elden Ring will get easier. And once you do defeat him, it will be immensely satisfying.
If you’re interested, I recently did a challenge run. I beat all the bosses on new game plus with the hud turned off. I also didn’t use healing potions or summons. Check out my Mohg battle below.
