How to Defeat Mohg, Lord of Blood

This is a guide to accessing and defeating Mogh, Lord of Blood. He was originally an optional and extremely difficult boss. Now, players must defeat him to access the Shadow of the Erdtree DLC. If you are returning to Elden Ring after a full playthrough the quick and dirty is that you must defeat Starscourge Radahn & Mogh, Lord of Blood then enter the Land of Shadow through the large egg Mohg guards.

Access to Mohg is usually quite difficult. His underground lair is normally only accessible once you've unlocked the Mountaintops deep into a playthrough [Map Link] but luckily we can get in early by doing Varre's questline. This gives us easy access to this late game zone after only completing Stormveil Castle.

Having finished Stormveil Castle be sure to return to Roundtable Hold and talk to the Two Fingers about your victory. Varre moves to his new location in the Rose Church which couldn't be simpler to find. Look for the large island directly south of Raya Lucaria Academy in Liurnia [Map Link].

Speaking with Varre, he asks what you thought of the Two Fingers. Choose "They didn't seem right" when prompted and Varre. This vaguely assigns your next task to invade 3 other players using the Festering Bloody Finger's he gives you. You do not have to engage with the online component as you can do the NPC invasion available in Altus Plateau [Map Link] instead. If you have access to online play, you do not have to win the 3 invasions to progress, simply participate in them.

Varre assigns you a final task before you can enter Mogh's Palace after completing your invasions. Acquire the blood of a Maiden. Lucky for you, there is a freshly dead Maiden in the Church of Inhibition [Map Link]. You do have to fight the invader Vyke to freely access this church but you shouldn't have major problems with him if you're following one of our build guides.

With maiden blood in hand return to Varre and become anointed. This gives you access to an infinite supply of invasions for those interested in PvP and talking to him again rewards you with the Pureblood Knight's Medal. When used the Medal sends you to the base of Mohg's Palace so you now have instant access to the area whenever you'd like and can ascend to fight Mohg, Lord of Blood.

Getting to the Moghwyn Palace is a relatively simple endeavor compared to defeating Mohg, Lord of Blood which is going to be considerably more challenging. In the original release of Elden Ring, Mohg was an entirely optional late game fight. Now he is required to access the Shadows of the Erdtree DLC. This means that he is second in difficulty only to the final bosses of Elden Ring and Malenia (A much harder optional boss). To start you off lets grab a couple unfair advantages that can be a big help.

Mohg's Shackle can be used to stun Mohg pinning him to the floor of his arena briefly up to twice during the first phase of his fight giving you the opportunity to inflict a large amount of damage. It is also especially helpful for setting up buffs before Mohg enters his phase 2 if the fight is drawn out. The Shackle found under the Leyndell Royal Capital in the sewers after the Underground Roadside Site of Grace and just before the Leyndell Catacombs entrance. It is guarded by one of the giant lobsters but can be picked up without defeating it.

Mix this Tear into your Wondrous Flask of Physick to entirely negate the damage from Mohg's transition into phase two as long as you drink it at some point during phase one. Mohg still heals as he normally does during his phase transition but you won't have to use many Sacred Flasks to absorb the damage. Obtain this Tear by defeating the invader at the Second Church of Marika on the Altus Plateau (Pictured below).

With both Mohg and Radahn defeated the way is now open to Shadows of the Erdtree by touching the hand at the back of Mohg's arena. Hopefully, this guide has been helpful to you and be sure to look out for our Elden Ring DLC coverage.
