Elden Ring boss guide – How to beat Mohg Lord of Blood in Mohgwyn Palace

Mohgwyn Palace in Elden Ring is actually a secret area. To get to it, you’ll need to acquire both pieces of the Haligtree Secret Medallion just so you can reach the Consecrated Snowfield. There, you have to find a well-hidden teleporter that will take you to this zone. Once you spawn in, continue following the main path, cutting through rivers of blood and cliffside filled with skeletons. Eventually, you’ll arrive at the boss’ arena.

Prepping for Mohg Lord of Blood in Elden Ring

You can do battle with Mohg Lord of Blood in Elden Ring whenever you wish. However, you might want to complete a few preparations to ensure success. First, there’s the Purifying Crystal Tear. You can pick it up if you go to the Second Church of Marika in Altus Plateau. This structure is fairly close to Mirage Rise (just look for wind currents that will let Torrent reach new heights).

When you arrive at the church, an NPC invader named Eleonora will attack you. Defeat her to receive the Purifying Crystal Tear. Combine this with any other tear via the Flask of Wondrous Physick to have an invaluable concoction.

Next, you should talk to the red NPC in Roundtable Hold who’ll give you the Sewer Gaol Key. Then, make your way to the Subterranean Shunning-Grounds in Leyndell Royal Capital. As you explore, you’ll encounter a bunch of crayfish down below. You can pick up the Mohg’s Shackle from behind one of the crustaceans who’s standing guard in front of the Leyndell Catacombs entrance.

Note: The Subterranean Shunning-Grounds also has you battling Mohg the Omen, another variant.

Elden Ring Mohg Lord of Blood boss fight – Phase 1

Now that you have both items, make sure they’re equipped and head inside Mohg Lord of Blood’s arena. Also, for the sake of clarity, I fought this boss while prioritizing ranged combat only, but I did take note of its abilities:

• Melee Combo – Mohg will usually do two swings with his weapon. The second swing will coincide with a lunge.
• Slash and Blast – When you’re in melee range, Mohg will swipe and mark the air to cause an explosion.
• Blood Splash – Mohg will throw blood pools at a wide location, which will cause flames to erupt. Your bleeding meter will also increase if you’re standing in the flames.
• Nihil Blood Rings – Mohg will periodically cast this spell, creating a red ring around your character.

Note: During phase 1, you can use Mohg’s Shackle to temporarily stun the boss. This is akin to the Margit encounter where you can only use this stun twice. Make the most out of it by unleashing brutal skills and combos.

Elden Ring Mohg Lord of Blood boss fight – How to negate the Nihil Blood Rings

Mohg’s Nihil Blood Rings is a deadly spell. When your character only has two rings, nothing would happen and you don’t need to worry. But, once you have three rings around you (at around 50% of Mohg’s HP), he’ll channel a destructive ability that will greatly damage you while healing himself. Since you have three rings, then you’ll have no choice but to waste three flasks just to keep your HP in tip-top condition.

Thankfully, we can counter the Nihil spell in Elden Ring. Remember the Purifying Crystal Tear? If that’s one of the effects of your Flask of Wondrous Tears, you can use the brew just as Mohg is about to cast Nihil.

When this happens, a barrier will protect you completely from damage. Even better, Mohg will continue casting, allowing you to strike him with impunity during the sequence. Sadly, I didn’t capitalize on this and I was still firing arrows. You should definitely be more aggressive in melee, if only for a short while.

Elden Ring Mohg Lord of Blood boss fight – Phase 2

After casting Nihil, Mohg will enter phase 2. He’ll gain a few abilities as well:

• Bleeding Slash – Mohg’s melee swipes will also leave trails of blood.
• Skewer – If you see the boss set to charge, cancel whatever you’re doing and prepare to dodge out of the way.
• Blood Rain – The boss will float in the air and spray blood in a wide arc.

I was mostly staying clear of Mohg’s melee, all while avoiding the Skewer and Blood Rain attacks. I simply shot a few times, then I sprinted to the opposite side of the arena before peppering him with a couple of arrows. I just repeated these steps until he died.

After defeating Mohg the Blood Lord in Elden Ring, you’ll receive the Remembrance of the Blood Lord. You can exchange it for:

• Mohgwyn’s Sacred Spear – Requires STR 24, DEX 14, and FAI 18; scales with STR D, DEX D, and FAI D.
• Bloodboon – Requires FAI 14.

Likewise, you’ll obtain Mohg’s Great Rune. To activate it, just head to the Divine Tower of East Altus. It’s the other path from Leyndell Royal Capital Outskirts, not the one heading to the Forbidden Lands/Grand Lift of Rold. You can’t miss it since it’s also the same place where you activated Morgott’s Great Rune.

When equipped and with a Rune Arc used, Mohg’s Great Rune in Elden Ring will give a blood blessing to your Spirit Ash phantoms.
