Immediate Answer: How to Beat Messmer the Impaler (True Ending Boss)
The true ending boss in Elden Ring’s Shadow of the Erdtree DLC is Messmer the Impaler, a two‑phase encounter that mixes swift melee combos with ranged fire and lightning attacks. To win, keep your Vigor above 55, equip a high‑bleed weapon like Rivers of Blood with Bloodflame Blade, and stay mobile to dodge his spear thrusts in phase one and his fire breath sweeps in phase two. Use the Miquella’s Needle at the Church of Inhibition before the fight to prevent the Frenzied Flame and unlock the true ending.
Preparing Your Build: Stats, Gear, and Ashes of War
Start with a Vigor of 60 to survive Messmer’s heavy hits. Endurance 40 lets you roll through his combos without stamina starvation. Aim for Strength 55 and Dexterity 45 to wield Rivers of Blood effectively; this split gives you both physical damage and the speed needed for quick ripostes. Faith 30 unlocks the Bloodflame Blade ash of war, adding fire damage that synergizes with bleed. Keep Arcane around 20 to improve item discovery for the Remembrance drop.
Weapon: Rivers of Blood (Katana) + Bloodflame Blade (Ash of War). This setup applies rapid bleed buildup while the fire ash deals extra damage over time. If you prefer a greatsword, the Blasphemous Blade with its fire wave and life steal works well, but its slower swing speed makes dodging harder.
Armor: Choose a set with high physical negation and decent fire resistance, such as the Lionel’s Set (physical 28.5, fire 18.2) or the Tree Sentinel Set (physical 30.1, fire 16.8). Keep equip load under 70% to maintain fast rolls.
Talismans: Radagon’s Scarseal (boosts Strength, Dexterity, Intelligence, Faith at the cost of increased damage taken) pairs well with the Crimson Amber Medallion (+10% HP) and the Shield of the Greatsword (+20% block potency). If you rely on dodging, swap the Shield of the Greatsword for the Lord of Blood’s Exultation (attack power up when nearby enemies bleed).
Flasks: Use a mix of 6 Crimson Flasks (HP) and 4 Cerulean Flasks (FP) to sustain both healing and the Bloodflame Blade skill.
Phase One: Sword and Spear Combos – Telegraphs and Counters
Messmer opens with a fast sword triple‑slash (left‑right‑left) followed by a long spear thrust. The sword combo has a short wind‑up; listen for the metallic clang and roll through the final slash to avoid the follow‑up spear. The spear thrust is telegraphed by a slight rear‑step and a bright glint on the spear tip; roll to the side as he extends his arm.
After the spear, he often chains into a sweeping overhead slash that covers a wide arc. This attack has a longer wind‑up; you can either roll backward or, if you have enough stamina, perform a guard counter with a shield equipped with the Shield of the Greatsword talisman.
When Messmer lowers his spear and plants it into the ground, he prepares a jumping slam. The jump is preceded by a small hop; roll away from the landing spot.
Throughout phase one, maintain mid‑range distance (about 5‑6 meters). This lets you react to his sword combos while staying just outside his spear’s maximum range. Use quick hit‑and‑run tactics: land two‑three hits with Rivers of Blood after a successful dodge, then retreat to reset.
If you have the Bloodflame Blade active, each hit applies both bleed and fire, accelerating his health drain. Aim to keep the bleed proc active; after three successive hits, the bleed will trigger for a large burst of damage.
Phase Two: Fire Breath and Lightning Storm – Managing Space
At roughly 60% health, Messmer enters phase two, gaining a fire breath attack and a lightning storm summon.
Fire Breath: He rears back, inhales deeply, then exhales a cone of flame roughly 120 degrees wide and 8 meters long. The inhale is audible and his chest glows orange. Roll to either side as soon as you see the inhale; the flame’s hitbox lags slightly behind his head, so a side roll is safer than a backward roll.
Lightning Storm: After the fire breath, Messmer plants his spear into the ground and summons three lightning bolts that strike in a triangular pattern around him. The summoning is signaled by a bright blue aura around his feet and a short chant. When you see the aura, sprint outward to increase distance; the bolts have a small delay before impact, giving you about 1.2 seconds to escape the zone.
He also retains his phase one melee combos, but now they are interspersed with the ranged attacks. After a fire breath, he often follows with a quick sword slash; anticipate this by preparing to roll as the flame ends.
Positioning is key: stay on the periphery of the arena, using the pillars near the entrance as cover to block the fire breath’s line of sight. When the lightning storm begins, move to the opposite side of the arena from where the bolts are summoned; they always appear relative to Messmer’s position, not the arena’s center.
Continue to apply Rivers of Blood with Bloodflame Blade. The fire damage from the ash stacks with the boss’s own fire breath, causing additional damage over time. When you see an opening after a dodged lightning bolt, unleash a jumping attack (press R1 + jump) to close distance and deliver a critical hit.
If your FP runs low, switch to a standard heavy attack with Rivers of Blood; the bleed buildup still works without the ash, and you can conserve FP for occasional Bloodflame Blade bursts when you need extra pressure.
Post-Boss: Claiming the True Ending Rewards
Once Messmer’s health reaches zero, he staggers and drops the Remembrance of the Impaler. Interact with the remembrance at any Roundtable Hold to exchange it for either the Impaler’s Great Sword (a massive greatsword with high physical damage and a unique fire‑based skill) or 15,000 runes.
The true ending cutscene then plays, showing the aftermath of your choice and granting the “Age of the Duskborn” achievement. This ending also unlocks the hidden DLC weapon, the Serpent‑Hunter’s Greatbow, which can be obtained from the statue near the Miquella’s Needle location after the cutscene.
