Elden Ring Great Runes Guide: What Each One Actually Does (and When to Burn a Rune Arc)

Morgott's Great Rune raises your maximum HP by 25%. Not for three minutes, not until you get hit — until you die. And a huge share of players roll credits without ever activating it, because FromSoftware buried the whole Great Rune system under three separate steps, an unmarked tower on the far side of the map, and a consumable everyone hoards like it's the last elixir in a JRPG they'll never actually drink.

That's the tragedy of Great Runes: they're the single largest permanent-feeling buffs in Elden Ring, and the friction around them convinces most people the system is optional flavour. It's not. Here's how it works, what every rune actually does — with the verified numbers — and when spending a Rune Arc is correct instead of precious.

How Great Runes actually work

Three steps, and the game clearly explains about one and a half of them:

1. Kill a shardbearer. The demigod bosses each drop a Great Rune — Godrick, Radahn, Rykard, Morgott, Mohg, Malenia, and Rennala (hers is a special case we'll get to).
2. Restore it at its Divine Tower. A freshly dropped rune is "devoid of any benediction" — a dead item. Each one names the tower you need in its own description, and until you climb it and select "Restore the power of the Great Rune," the rune does nothing.
3. Equip it at a Site of Grace, then consume a Rune Arc. Equipping alone does nothing — this is the step that loses people. The blessing only switches on when you burn an Arc, and it lasts until you die or swap to a different rune.

That last clause is the important one. There's no timer. A Rune Arc'd blessing survives resting at graces, fast travel, everything short of death. If you're having a careful session, one Arc can cover hours.

Where each rune gets restored:

Two housekeeping notes. First, holding two Great Runes — restored or not — is what unseals Leyndell's front gate, which is why the critical path runs through two shardbearers before the capital. Second, New Game Plus wipes the lot: every rune must be re-earned and re-restored each cycle, which matters for how you value them (more on that under Radahn's).

The Rune Arc economy

The reason people never activate Great Runes isn't the towers — it's the Arcs. They feel rare, so they get hoarded, so the system goes unused. The actual supply is healthier than it feels:

• Twin Maiden Husks at the Roundtable Hold sell five at 4,000 runes each. That's trivial money by mid-game.
• Guaranteed pickups sit on corpses in the Sellia Crystal Tunnel and Siofra River, and Shadow of the Erdtree tucks one on a body near the Fort of Reprimand.
• Rats drop them at roughly a 1% rate — the Weeping Peninsula's Earthbore Cave and the rampart gaol stretch of Castle Morne are the usual farming spots.
• Multiplayer prints them. Win a boss as a co-op summon and you get one. Successfully invade — the host dying to anyone counts — and you get one. Kill an invader as a hunter, one more.

If you play any co-op at all, Arcs are functionally infinite — a couple of evenings helping people past Margit will stack more than you'll ever spend. Purely offline players should still relax: you can hold 99, you'll find a steady trickle, and dying with a blessing active costs you one consumable, not a build.

One more detail straight from the item description: popping a Rune Arc with no Great Rune equipped still slightly raises your maximum HP. It's a small courtesy buff, not a strategy — but it means an Arc is never a fully dead button press.

Godrick's Great Rune: forty stat points with an expiry date

The number: +5 to all eight attributes while active.

Five points in eight stats is forty levels' worth of raw attributes from one consumable, and you can have it before your first Golden Seed hits the flask. It fixes weapon requirements you're five points short of, pads Vigor when thirty is still a distant dream, and quietly buffs your defenses, since those scale off attribute totals.

The catch is that flat points age badly. The wiki notes pin the crossover precisely: from 16 Vigor onward, Morgott's rune gives more HP than Godrick's +5 Vigor does, and Radahn's 15% beats the +5 on HP from 37 Vigor and on FP from 40 Mind. Soft caps do to Godrick's rune what they do to every flat bonus — shrink it relative to percentages as your sheet fills out.

So Godrick's is the early-to-mid-game rune, and it's excellent there. Twenty levels of survivability stats plus twenty levels of offense, at the exact point in the game where five points is the difference between wielding a weapon and looking at it.

Radahn's Great Rune: the percentage play

The number: +15% to maximum HP, FP and stamina.

This is Godrick's rune for grown-ups. Three pools, all percentage-scaled, which means it gets better every level you gain instead of worse. A hybrid build that actually uses its FP bar and sprints a lot extracts value from all three lines at once — it's the natural pick for spellblades and anyone running stamina-hungry colossal weapons alongside an Ash of War rotation.

Its real competition is Morgott's, and the honest comparison goes: if the only number you care about is HP, Morgott's 25% simply wins. Radahn's case is the spread — 15% on three bars beats 25% on one for characters who genuinely run out of FP and stamina in fights. Pure melee with a big flask? Take Morgott's. Everyone else, it's closer than the internet pretends.

Morgott's Great Rune: the biggest number in the system

The number: +25% maximum HP, applied multiplicatively after your other HP buffs.

That multiplicative wording is worth money. The 25% is calculated after things like the Crimson Amber Medallion and Erdtree's Favor have already raised your HP, so talisman stacking makes the rune's absolute value bigger, not smaller. On a 40 Vigor character it's roughly an extra hit and a half from every endgame boss — which, in a game where most deaths are two-hit sequences, is the difference between a panic roll and a corpse run.

Veterans of Dark Souls 3 will recognize the shape: this is basically the ember system, except you have to do the activating yourself. Morgott's drops late — he's the gate to the back third of the game — but from the moment you restore it at the Divine Tower of East Altus, it's the default answer to "which rune?" for most builds, most of the time.

Rykard's Great Rune: the dungeon sustain engine

The number: restores 80 HP plus 7% of your maximum HP every time you defeat an enemy.

Do the arithmetic on a mid-game health bar: at around 1,500 max HP, each kill returns roughly 185 HP. Clear a room of five imps in a catacomb and you've healed three-quarters of a flask charge without touching your flasks. That's the entire pitch — Rykard's rune converts exploration and dungeon-clearing into a self-sustaining loop where you arrive at every boss door with full flasks.

And that pitch has a hard ceiling: the heal triggers on kills, so it does nothing in boss fights. The wiki calls it effectively useless against bosses and that's the correct read. It also stacks with the same-flavored kill-heal items — Blasphemous Blade, Taker's Cameo, the Serpent-God's Curved Sword — and a full stack of those turns overworld Elden Ring into a game where your health bar only moves in one direction.

Use it for long clearing sessions, rune farming, and catacomb marathons. Swap off it before fog walls.

Mohg's and Malenia's: the two strange ones

Mohg's Great Rune is a multiplayer item wearing a demigod's name. Active, it grants a blessing of blood to phantoms you summon — their attacks gain extra blood loss buildup — and successful invasions award you a Phantom Great Rune, a consumable that sacrifices your HP to empower nearby enemies, which only matters in invasion scenarios. If you play strictly solo, this rune does approximately nothing for you, and that's not a hot take — it's what the item does. Co-op regulars who summon bleed-heavy friends get a real, if narrow, buff.

Malenia's Great Rune is the fascinating failure. It bolts Bloodborne's rally mechanic onto Elden Ring: after an enemy hits you, a window of roughly five seconds opens where your attacks restore lost HP, up to the amount you had before the hit. The restore per swing depends on the attack type and weapon class — jumping and charged attacks recover noticeably more — rather than the damage you deal, and multi-hit strings rally fastest. The price: while the rune is active, your Flask of Crimson Tears heals for less.

The problem is the exchange rate. Bloodborne was built around trading hits; Elden Ring's endgame is built around not getting hit, because getting hit twice kills you. Paying reduced flask power — your most reliable survival tool — for a five-second rally window in a game this bursty is a bad trade for most builds. There's a genuinely fun aggro-tank archetype in there for players who guard-counter with heavy weapons and never stop swinging, and the rest of us should treat it as a curiosity from the hardest optional boss in the base game.

The two that aren't buffs at all

The Great Rune of the Unborn — Rennala's — never touches a Rune Arc. It's active the moment she dies, needs no Divine Tower, and its entire function is unlocking Rebirth: talk to Rennala in the Raya Lucaria Grand Library and you can reallocate your attributes for one Larval Tear, or change your appearance for free. It's the respec system. Beating Rennala early is worth it for this alone, because it converts every build mistake from permanent into a Larval Tear's worth of inconvenience.

Miquella's Great Rune is Shadow of the Erdtree's contribution, and it breaks every rule above. It's classified as a tool, drops from the Scadutree Avatar at the Scadutree Base, cannot be restored at a tower, cannot be activated with a Rune Arc, and grants zero passive stats. It has exactly one use: during the fight with Promised Consort Radahn, using it nullifies Miquella's charm. That's a specific mid-fight mechanic counter for the DLC's final boss, and if you're headed there, having it in your pocket is the difference between playing the fight and playing his fight.

Which rune should get your Rune Arc

The honest decision tree:

• Before Leyndell, or any time a weapon requirement is five points away: Godrick's. Forty stat points is unbeatable value while your sheet is small.
• Melee build at or past the Vigor soft cap: Morgott's. The 25% is the biggest survivability number a single item gives you, and it's multiplicative with your HP talismans.
• Hybrid or caster who actually drains FP and stamina bars: Radahn's. Three 15% pools beat one 25% pool if you genuinely use all three.
• Clearing catacombs, farming, long exploration sessions: Rykard's. Kill-heal sustain keeps your flasks full for whatever's at the bottom of the dungeon.
• Co-op summoner with bleed-friendly partners: Mohg's, and only then.
• Aggressive guard-counter build that wants a Bloodborne cosplay: Malenia's, eyes open, knowing your flask got worse.

And the meta-advice that matters more than any row above: actually spend the Arcs. The system's biggest trap isn't picking the wrong rune, it's dying at 99 held with zero active, having banked a buff economy you never used. A physick tear mix lasts three minutes and people re-mix it constantly; a Great Rune lasts until death and people treat it as too expensive to touch. The math runs the other way.

Quick Action Checklist

• After every shardbearer kill, read the rune's description — it names its Divine Tower — and go restore it before moving on. The towers are quick detours, not dungeons.
• Buy the five Rune Arcs from the Twin Maiden Husks (4,000 runes each) the moment the price stops hurting.
• Run Godrick's until 16 Vigor for HP purposes and mid-30s stats generally, then reassess against the percentage runes.
• Default to Morgott's once you have it; switch to Radahn's only if your FP and stamina bars are real constraints.
• Equip Rykard's for farming and dungeon marathons, and swap before boss fog.
• Kill Rennala early even on a strength build — the Great Rune of the Unborn is the respec system and it costs nothing to hold.
• In the DLC, don't skip the Scadutree Avatar: Miquella's Great Rune is a one-button counter to a final-boss mechanic.
• If a boss has killed you three times in a row, that is exactly the moment to burn an Arc, not save it.
