Grants a blessing of blood to phantoms

Mohg's Great Rune is a Great Rune and Multiplayer Item in Elden Ring. Great Runes in Elden Ring are special items dropped by Demigod Bosses that can be equipped to acquire special passive bonuses.

 

A Great Rune of the shardbearer Mohg.
Its blessing grants a blessing of blood to summoned phantoms, and imparts a Phantom Great Rune upon successful invasion.

Mohg and Morgott are twin brothers, and their Great Runes are naturally similar.

But Mohg's rune is soaked in accursed blood, from his devout love for the wretched mire that he was born into far below the earth.

 

Where to find Mohg's Great Rune in Elden Ring

 

Elden Ring Mohg's Great Rune Use

Mohg's Great Rune allows the user to grant the Blessing of Blood to summoned spirits (from Spirit Ashes or Legendary Spirit Ashes) or native monsters/bosses from an invaded world.

The Blessing of Blood makes it so every time those blessed by it kill an enemy, the user of the Great Rune will be healed by 10% of their maximum HP. Additionally, when blood-loss is inflicted on the vicinity of a blessed individual, the blessed individual(s) will gain a damage buff similar to that of Lord of Blood's Exultation for approximately 20 seconds.

When invading with the rune's effect active, the invader gets 3 phantom great runes to apply the blessing to monsters in melee range, which also costs on first cast a chunk of health, subsequent casts are free.
For a more detailed explanation of the effects of this rune, see below.

If you want to use Mohg's Great Rune after you acquired it from Mohg, Lord of Blood, you will need to restore its power (similarly to other Great Runes) by visiting the appropriate Divine Tower; in this case, the Divine Tower of East Altus. To reach the location, follow the Capital Outskirts ramparts to the lift that leads to Forbidden Lands, but instead of descending through the lift, go south-east and towards the other doorway which will lead you directly to the Divine Tower. If you already reached the Forbidden Lands' starting Site of Grace, you can also teleport to it and backtrack through the lift. Be wary that you will be required to defeat the Fell Twins boss as you cross the bridge in order to progress to the tower itself.

 

Mohg's Great Rune Usage and Effect Details

All functionality of the Great Rune is not enabled if a Rune Arc is not used (even though when invading or being summoned, other Great Runes' effects are disabled, this is the only one whose effect stays active and requires a Rune Arc to be used BEFORE the invasion takes place for it to activate).

 The effects of this Great Rune are detailed below:

  1. When in your world, Summoned Spirits (from Spirit Ashes items) automatically gain the buff called Blessing of Blood.
  2. The Blessing of Blood has the following effects:
    • A subtle red smoke aura envelops those affected. This is the indication that Blessing of Blood effect is active.
    • Each enemy they kill while you are in close proximity, heals you by 10% of your maximum HP. This effect stacks with other ''life-steal'' effects and looks the same as them, like the talisman Taker's Cameo.
    • Whenever they inflict the blood loss status effect (inflict meaning that the damage attached to the status is triggered and its status bar ''filled''), they gain a damage increasing buff, similar to (and presumably stacking with) the talisman Lord of Blood's Exultation (should the Spirit be the Mimic Tear Ashes with that talisman equipped). Visually, this effect looks like red vertical lines appearing around the player's body. Further testing required to verify exact quantity of damage increase.
    • The duration of the Blessing of Blood itself is INFINITE.
    • The duration of the damage increasing buff that occurs after blood-loss is applied is around 20 seconds (same duration as the talisman Lord of Blood's Exultation). This means the buff can be indefinitely be reapplied, assuming blood-loss status effect keeps being triggered.
    • The triggering of the blood-loss effect to activate the damage increase buff just needs to happen in close proximity to the blessed individual, and does not need to be applied directly by the blessed individual himself. For example, a host player (which does NOT gain the effect of the Blessing of Blood) can trigger blood-loss next to an allied Spirit that he summoned, and the blessed spirit will receive the damage increasing buff anyway.
  3. It DOES NOT apply the blessing to the player nor any other players. Only spirits summoned by the player in their world or monsters and bosses native to the invaded world when invading gain the Blessing of Blood. This makes the Great Rune useless in single-player if the player is not summoning spirits, and useless when the player is invading if no monsters or bosses to bless are present.
  4. The following additional effects apply when the player is invading another player's world, with the Great Rune active (meaning the player used a Rune Arc):
    • As he arrives to the invaded world, the player receives 3 copies of a temporary unique consumable item, called Phantom Great Rune. When consumed, the player plays the same animation as consuming a Rune Arc, generating a small red area-of-effect which buffs any monsters or bosses (like Night's Cavalry) in close proximity to the player with the Blessing of Blood. For the exact effects of the Blessing of Blood, see above. When invading, this is the only way to apply the Blessing of Blood to the monsters and bosses.
    • If the player does not use the Phantom Great Rune during their invasion, the effect of Mohg's Great Rune is essentially wasted, as the Phantom Great Runes disappear from the Player's inventory when returning to their world. The Great Rune effect still persists after a failed invasion, so subsequent invasions will still grant the Phantom Great Runes until the player dies in their own world.

 

Elden Ring Mohg's Great Rune Notes & Tips

  • Since the effect only applies to allied Non-Player-Characters (summoned as Host, or native to the world as Invader), if none are present, the effect of the rune is wasted.
  • If the player himself wishes to have effects similar to the ones granted by the Blessing of Blood, the talisman Lord of Blood's Exultation gives the same damage boost every time blood-loss is applied in the vicinity and the talisman Taker's Cameo heals when enemies are defeated in the vicinity. If the player were to summon a Mimic Tear  spirit (which copies the current equipment of the player who summoned it), those effects would stack with the Blessing of Blood effects powering the Mimic Tear even more.
  • Since the duration of the Blessing of Blood buff is infinite, when the player is invading another player's world it's a good idea to buff monsters/bosses the player expects the invaded players to encounter either to set up ambushes or weaken the invaded player. Confirmation is required of whether or not blessed monsters retain their blessing even if the invader (the user of the Phantom Great Rune) dies and leaves the world.
  • In short, the afore-mentioned effects leads to a few possible uses for this Great Rune:
    1. If the player is the Host, it is useful to increase the damage of summoned spirits, assuming either the spirit or the Host has the means of applying blood-loss. But even if no blood-loss is present, it can be very useful for giving summons the ability of healing the Host for every enemy they kill, aiding the survivability of the Host. This is a strong buff given the player has the chance to defeat many monsters in-between bosses, and most of the time Spirits are available for summon is to fight big groups of enemies. If the fight were to be against only a boss though, the healing effect would be far less useful (since once the boss dies the fight is over and a 10% HP heal becomes irrelevant).
    2. If the player is Invading another player's world, it is useful only to boost the damage of monsters and bosses if blood-loss is triggered in their vicinity. The main problem with this is players move a lot and it is not rare for a blood-loss to trigger when the enemies are too far to benefit from it; specially since NPCs are not good at inflicting blood-loss to experienced players. Either way, the life-steal effect does apply to the monsters too, but since the monsters are only hostile to the rival player, they'd have to sucessfully defeat a player which, again, is a hard feat to pull off for a monster, specially since the monster has to be the one that lands the killing blow for the heal effect to activate. As such, and maybe ironically, it seems this rune is far more useful for when the player is the Host, rather than invading.

      kinda wish all great runes had an effect in multiplayer like this. morgott's rune could give you consumables that heal nearby allies, for instance.

        Single most useless rune. An effect on kill for something u summon for a single boss is the dumbest idea.

          The fell twins shouldn't be too much of a concern for anyone. They obviously have a larger health pool than the enemy Omen as long as you kill the first one before the sneaky one reaches you and you have to fight both at the same time you'll be golden.

            Approx 30% increase in summon damage. Tested it on rot doggo and noble sorcerer Ash on the nobles near the tutorial area site of grace.

              This is a necessity for any invaders...

              Because its the only great rune that does something while invading.

                As if the adorable murder-blob that is the jellyfish wasn't OP enough, slap this on and she basically is given DOOM/Quake's railgun. Give this to a Mimic Tear and you're already wearing the Lord of Blood's Exultation + using Rivers of Blood and any other katana? You won't even need to fight bosses. Just give them a lovetap to cause the Mimic to aggro onto the boss, and then step way back as it bulldozes through just about all of them that allow an NPC summon. If you're wearing Godskin Swaddling Cloth, plus the stuff above, then the Mimic will almost literally heal itself faster than it can take damage in many cases.

                  Would this pair well with the Dung Eater summon? He can bleed enemies on his own without the player’s help. Also does anyone know how much of a damage bonus it is? Is it large enough to make a difference?

                    His gold summon sign is available right outside Godrick's room after becoming the carrier of the Frenzied flame. Very cool.

                      Ok imma dumb it down for you friends;

                      You need to use a rune arc before invading. Then, when invading, you'll get 3 items to use that boost nearby ennemies. Using the item once take a chunk of your max health but wont for the second and third use. You alo get healed when the host or phantom kill ennemies.

                        Fromsoft should buff this rune. Just give it the healing factor when killing players too and maybe give it a gravelord like effect too, like using it places a red sign to let other players invade your world while its active.

                          It's a damn shame this rune doesn't provide the buffs to the player while they're invading a Host. You'd expect it to considering it's part of the Varre/Mohg questline. 10% HP recovery when defeating a summon or hunter would be sick.

                            Invade in Elphael -> buff cleanrot knights, tree spirit with crossbows and keep one if host goes for revenants -> easy rune arcs farm

                              You can remove the debuff from using phantom great runes by activating a phantom finger

                              Been using a random spear with seppuku on to activate the effect and the health on kill has helped me once or twice

                              Though this is still a super gimmicky rune, the concept is really cool. Its kinda fun to run around just before where the host is and buffing up specific enemies, I hope they rework or buff this at somepoint so its less useless.

                                So, do you lose the Mohg's Great Rune effect when you die as an invader or just when you die as a host in your own world (just like how you lose any other Great Runes)?

                                  Watered down and nearly worthless "gravelording"

                                  I see people saying that this could be of use against ganks. But most actual ganks will have already killed all the mobs by the time you arrive. The entire idea of relying on pve as an invader is similarly pointless, tedious and boring for everyone. Because the host usually will back away from hostiles and wait by the grace where he can summon more goons to kill you. They dont need to do anything but wait. And that is what they will do most of the time if they see you.

                                  The 10 percent hp penalty is salt in the wound. Invaders are meant to lose, and this rune will help make that process easier.

                                    seems like the only one to use for an invader since you can get some advantage in areas with some mobs. you do lose 10% hp which sucks but you don't have to pop the phantom rune if you don't want to

                                      I think the only invasion item being Moghs Great Rune and putting no duel area in the game shows they didn't want duels from ER even if they allowed stuff like duels in previous DS titles with PvP arenas. They want invaders to fight with and even buff the AI to help defeat the host. They expect invaders to bring strong weapons because they'll know its 2v1-3v1 fights. This only works if your trying to invade people not seeking PvP and playing thru the game naturally tho.

                                        Not that useful, but still it is the only thing invaders have going up against gank squads. I find it to be good for buffing retarded stone cats in catacombs

                                          So you could activate this with a Rune Arc, invade someone's world, and then buff the enemies quite easily by inflicting blood loss on yourself with the Seppuku Ash of War as well as triggering the player's Lord of Blood's Exultation

                                            I found that the farming spot in Mohgs area is the best place to use this great rune for PVP. Since there are a hoard of enemies that use bleed you can buff them all and then gank gankers. Definitely the most fun I have had in pvp so far.

                                              Still have yet to find any decent use for this as an invader.
                                              It lowers your max Hp when used, which is horrible - you're already outnumbered and everything 2 shots you anyways, in exchange for semi buffed mobs that only help if you run a bleed build ?

                                                It's probably important to note it doesn't disappear when you die in an invasion, as in if you activate a rune arc before invading, it's essentially active until you die in your own world.

                                                  In simple terms: is there a benefit to using this rune if I'm fighting Malenia with Tiche? Does it only give benefits if I bleed her?

                                                    sad story when you aquire your third great rune of the game and find it to be worse than the first one again. then google out of frustration what the others do and discover that godricks rune is actually the best and only viable rune in the game.

                                                      I can only think of using this for trolling or doing Stacked PVE fights with your friends. Get summoned up and buff up a mini boss and duel 2 other players. Evens the odds a lot when you have to deal with 2 players most times you invade. Problem is you need a rune arc for it. Best use is monster fight club for sure.

                                                      • I guess it's good for pvp. I'm still rocking Godrick's, everything else is has just been meh. At lvl 150 Godrick's still provides me with the best gains. Life leech, HP and Stamina I can get from weapons and talismans if needed. I guess you could use this when summoning your spirit ash for a boss fight but that would require you to spend at least 2 Rune Arc's unless you wan't to keep using Mohg's rune after the fight, also assuming you won't die during the fight.

                                                                Does Blood Loss nearby specifically mean when the Blood Loss meter fills? Because the Helm called “Black Dumpling” states when you are have built up Madness you get a damage buff but this buff applies for even the smallest amount of Madness build up and doesn’t require you to fill the bar. Do the Poison and Rot damage buffs only apply when something nearby actually has contracted the poison or as long as it has build up?

                                                                  • Anonymous

How much the buff? Wish I knew. (They glow red after the buff). And the other item is Phantom Recusant Finger × 3, which lets you respawn in a different part of the area. Good if you're cornered although the animation is a bit slow so they can still get you. Kinda fun pvp rune but kinda situational. Wish I knew how far the buff reaches too.

                                                                      • Anonymous

                                                                        There was no noticeable healing on the summon itself during testing. I am 99.9% sure this rune only heals you, the summoner.
                                                                        Spirit Ash summons had no increase in damage when using the rune, whether I bled nearby enemies/let them bleed enemies or not.
                                                                        I can't speak on co-op play but if you're playing solo with spirit ashes, this is just a healing rune.
                                                                        if you're playing pvp invasions, it's cool as heck.

I think blessing of blood to summoned phantoms is the same effect of Phantom great rune which increase attack power to summoned phantoms when there is blood loss nearby and heal your summon when they defeat enemy.

I think a blessing of blood to summoned phantoms is the same from Phantom Great Rune which boosts summoned phantoms attack when there is blood loss nearby and recover HP when your summon kill enemy.

If you attack and enemy and apply them bleeding (u know, that thing of losing a certain % of hp) while you have a spirit summoned nearby, it seems to buff them (that red aura they have becomes bigger and redder). I am not sure how exactly what the buff does but it seems to last 30ish seconds or so, and applying bleeding during that buff seems to refresh it's duration

                                                                                • Anonymous

                                                                                      Just figured it out. So once you invade someone, it gives you an item called the "Phantom Rune". You can go into your inventory and use it. Once you use it, the monsters around you become stronger. But it takes some of your health in doing so. Would be great to use in an area where there's a mini boss or multiple strong opponents in the area.
