Introduction: Preparing for the Shadow of the Erdtree Boss Rush
Elden Ring’s Shadow of the Erdtree DLC remains one of the most challenging expansions in FromSoftware’s history. Whether you’re returning to the Lands of Shadow for a fresh run or attempting a boss rush challenge, this guide provides exact step-by-step strategies for conquering each major boss encounter. We’ll cover optimal builds, weapon selections, Spirit Ash recommendations, and detailed phase breakdowns so you know exactly what to do at every moment.
Before diving into individual boss strategies, ensure your character meets these baseline requirements: Level 150 minimum (Level 170+ recommended), at least 50 Vigor, and a collection of Scadutree Fragments — aim for at least Scadutree Blessing Level 10 before attempting the later bosses. Collect Revered Spirit Ashes to upgrade your Spirit Ash summons to their maximum DLC potency.
Optimal Build Setup for the Boss Rush
Primary Build: Strength/Faith Hybrid
This build offers the best combination of raw damage, survivability, and versatility across all boss encounters in the DLC. Here is the exact stat allocation at Level 170:
- Vigor: 60
- Mind: 25
- Endurance: 30
- Strength: 54
- Dexterity: 16
- Intelligence: 9
- Faith: 40
- Arcane: 9
Right Hand Weapons: Blasphemous Blade +10 (primary), Greatsword of Solitude +10 (DLC weapon, obtained after defeating Commander Gaius). The Blasphemous Blade’s weapon art, Taker’s Flames, provides consistent healing on kill and excellent range. The Greatsword of Solitude deals bonus damage to several DLC bosses weak to holy damage.
Left Hand: Erdtree Greatshield +10 (for blocking specific high-damage attacks), Finger Seal +10 (for incantations).
Armor Set: Tree Sentinel Set provides excellent physical and holy damage negation. Swap the helmet for the Crimson Hood if you need extra HP.
Talismans: Dragoncrest Greatshield Talisman (physical damage reduction), Shard of Alexander (boosts weapon art damage by 15%), Erdtree’s Favor +2 (HP, stamina, equip load), and Ritual Shield Talisman (damage reduction at full HP).
Incantations: Golden Vow (damage and defense buff, lasts 80 seconds), Flame Grant Me Strength (fire and physical damage boost), Lord’s Divine Fortification (holy damage reduction for specific fights), and Erdtree Heal (emergency full heal).
Spirit Ash: Mimic Tear +10 remains the strongest option. With the Blasphemous Blade equipped, your Mimic will spam Taker’s Flames and self-heal continuously. For players who prefer a more aggressive summon, Black Knife Tiche +10 applies a percentage-based HP drain that’s devastating against high-HP bosses.
Alternative Build: Dexterity/Bleed
If you prefer faster combat, run dual Rivers of Blood +10 or the DLC’s Curseblade Cirque. Allocate 60 Vigor, 20 Mind, 25 Endurance, 16 Strength, 55 Dexterity, 45 Arcane. Use the Lord of Blood’s Exultation talisman, White Mask, Rotten Winged Sword Insignia, and Millicent’s Prosthesis. Note that several DLC bosses resist bleed, making this build harder for certain encounters.
Boss-by-Boss Breakdown
Boss 1: Divine Beast Dancing Lion
This is typically the first major boss you encounter in Belurat, Tower Settlement. The Dancing Lion cycles through three elemental phases: lightning, frost, and wind.
Phase 1 (Physical + Lightning): The boss opens with a series of lunging bite attacks. Roll to the right on each lunge — the hitbox extends further to the boss’s left side. After three consecutive lunges, the Dancing Lion pauses for approximately 2 seconds. This is your punish window: use a charged R2 or Taker’s Flames. When the arena fills with lightning particles, the boss will perform a large AOE slam. Sprint directly away from the boss (do not roll) until the lightning dissipates, then close distance for one attack.
Phase 2 (Frost Transition at 65% HP): The boss roars and the arena temperature drops visually. Frost breath attacks come in two patterns: a 180-degree sweep (roll through it toward the boss) and a straight-line blast (sidestep left). The frost buildup is dangerous — equip Stalwart Horn Charm or consume Thawfrost Boluses. After every frost breath, the boss is vulnerable for 3 seconds. Land two R1s or one weapon art.
Phase 3 (Wind Phase at 30% HP): Wind tornados spawn around the arena. Stay in the center of the arena to avoid being pulled into wall damage. The boss gains a vacuum attack that sucks you in — when you see the inhale animation (the lion head opens wide), roll backward three times consecutively. Immediately after the vacuum, the boss exhausts itself for 4 seconds. This is your longest punish window in the entire fight. Use Golden Vow + Flame Grant Me Strength + Taker’s Flames to deal massive damage.
Spirit Ash Timing: Summon your Mimic Tear immediately upon entering the fog gate. The Mimic draws aggro during phase transitions, giving you safe windows to rebuff.
Boss 2: Commander Gaius
Located in the Shadow Keep, Commander Gaius rides a massive boar and combines gravity magic with devastating charge attacks.
Opening Strategy: Gaius always opens with a long-range charge. Do NOT roll early. Wait until the boar is approximately 3 character-lengths away, then roll to the left. Immediately punish with one R1 as Gaius passes by. He will circle back for a second charge within 5 seconds — repeat the same dodge timing.
Gravity Magic Phase (75% HP): Purple orbs begin orbiting Gaius. These orbs have tracking and will home in on your position. Sprint in a wide circle around the arena rather than rolling. After the orbs dissipate (approximately 6 seconds), Gaius performs a gravity slam. Jump over the shockwave (do not roll) and punish with a jumping R2 for bonus poise damage.
Enraged Phase (40% HP): Gaius dismounts briefly and performs a three-hit combo: horizontal slash, vertical slam, gravity explosion. Roll right, roll right, then roll backward for the explosion. After the explosion, Gaius remounts with a 5-second animation — this is a massive punish window. Use your strongest weapon art twice.
Key Tip: Stay at medium range (approximately 5 character-lengths). Too close and the boar’s hitbox clips you during turns. Too far and you trigger the charge attacks more frequently.
Boss 3: Messmer the Impaler
The central antagonist of the DLC, Messmer is found at the top of the Shadow Keep. This is a two-phase fight with a cutscene transition.
Phase 1 — Messmer the Impaler: Messmer wields a spear with fire augmentation. His attack patterns are precise and punishing.
Opening: Messmer walks slowly toward you. He always initiates with a three-thrust combo. The timing is: roll at 0.5 seconds, roll at 1.2 seconds, roll at 2.0 seconds. All rolls should be to the right. After the third thrust, Messmer plants his spear in the ground and creates a fire pillar — roll backward once. You now have a 3-second window for two R1 attacks.
At 80% HP, Messmer adds a serpent summon attack. Red snakes emerge from the ground in a line toward your position. Sidestep left and continue approaching. The snakes have a fixed path and will not track after spawning.
At 50% HP, Messmer performs a grab attack (telegraphed by his left hand glowing red). This grab is a one-shot kill at lower Vigor levels. When you see the red glow, immediately roll backward twice. The grab has deceptive range — a single roll is not enough.
Phase 2 — Base Serpent Messmer: After the cutscene, Messmer transforms. His moveset changes entirely. He gains flight and ranged fire serpent projectiles.
The key pattern to learn: Messmer flies up, launches three fire serpents (roll left, roll left, roll right — the third serpent has reversed tracking), then dive-bombs your position. Roll forward through the dive-bomb to end up behind him. Punish with Taker’s Flames.
At 30% HP, Messmer enters a frenzy state with continuous attacks for approximately 8 seconds. Do not attempt to punish during this sequence. Focus entirely on rolling through attacks: the pattern is right, right, left, back, right, left, back, forward. After the frenzy, Messmer collapses for 5 seconds — this is your opportunity to deal maximum damage. Pre-buff with Flame Grant Me Strength during the frenzy’s final seconds if possible.
Spirit Ash Note: Your Mimic Tear will likely die during Phase 2. Ensure you deal at least 60% of Phase 1’s health before the transition so your Mimic survives long enough to split aggro in Phase 2’s opening.
Boss 4: Promised Consort Radahn
The final boss of the DLC. This is widely considered the hardest boss in all of Elden Ring.
Phase 1 — Radahn: Radahn uses his dual greatswords with gravity-enhanced combos. Every attack has a delayed timing designed to punish panic rolls.
Rule of thumb: count “one-Mississippi” after each attack animation begins, THEN roll. Radahn’s delays are consistently around 0.8–1.2 seconds longer than you expect.
Radahn’s four-hit combo sequence: overhead slam (roll left at delay), horizontal sweep (roll into him), rising slash (roll backward), and gravity slam (jump). After the gravity slam, Radahn recovers for 3 seconds. Land one Taker’s Flames.
At 60% HP, Radahn adds gravity orbs to his combos. These orbit him and extend the hitbox of his swings by approximately 50%. Increase your roll distance — roll twice for attacks that previously required one roll.
Phase 2 — Radahn + Miquella: At 50% HP, a cutscene triggers. Miquella empowers Radahn with holy magic. Radahn now deals split physical/holy damage, and his attacks leave golden residue on the ground that deals damage over time.
Equip Lord’s Divine Fortification before the cutscene if possible (it persists through the transition). This reduces his holy damage by 60% and makes the fight significantly more manageable.
New attack to watch for: Radahn raises both swords and Miquella creates expanding golden rings. There are three rings, each expanding outward. Roll through each ring as it reaches you — the timing is approximately 1.5 seconds apart. After the third ring, Radahn charges with a flying thrust. Roll to the left at the last moment.
At 20% HP, Radahn performs his ultimate attack: he leaps into the sky and crashes down as a meteor (similar to his base game move, but with added holy explosion). Sprint away the moment he leaves the ground. After the meteor impact, there is a secondary holy explosion after 2 seconds — continue sprinting. Once both explosions resolve, Radahn is vulnerable for 6 seconds. This is the longest punish window in the fight. Use Golden Vow + Flame Grant Me Strength + Taker’s Flames twice to close out the fight.
Final Phase Tip: Below 10% HP, Radahn becomes extremely aggressive with almost no recovery windows. Save your Flask of Wondrous Physick (Opaline Hardtear + Holy-Shrouding Cracked Tear) for this final push. Pop it, trade hits aggressively with Taker’s Flames (which heals you), and finish him before he finishes you.
General Tips for the Full Boss Rush
Flask Allocation: Run 10 Crimson Flasks and 4 Cerulean Flasks. The Blasphemous Blade’s passive healing reduces your reliance on healing flasks, while you need FP for weapon arts and incantation buffs.
Buff Sequence Before Every Boss: Golden Vow → Flame Grant Me Strength → summon Spirit Ash → enter fog gate. Golden Vow lasts 80 seconds, which is enough for most opening phases. Reapply during safe windows (phase transitions, boss staggers).
Scadutree Fragment Locations: Prioritize collecting fragments before attempting later bosses. Key locations include: Belurat church (1 fragment), Shadow Keep main gate (2 fragments), Church of the Crusade (1 fragment), Bonny Village (2 fragments), and the Specimen Storehouse (3 fragments). Reaching Blessing Level 15 before Radahn makes the fight substantially more forgiving.
Practice Sequence: If you’re struggling, fight the bosses in this order for a natural difficulty curve: Dancing Lion → Rellana (optional but recommended for practice) → Commander Gaius → Messmer → Radahn. Each boss teaches mechanics that prepare you for the next encounter.
With this guide’s exact sequences, builds, and timing windows, you have everything needed to conquer the Shadow of the Erdtree boss rush. Patience with roll timing, proper buff management, and knowing each boss’s punish windows are the keys to victory. Good luck, Tarnished.
