How to Defeat Rellana, Twin Moon Knight in Elden Ring
Whether you're a spellcaster or a melee-focused Tarnished, this guide will walk you through everything you need to know to overcome Rellana's graceful fury.
Who Is Rellana, Twin Moon Knight
Rellana is the younger sister of Rennala, Queen of the Full Moon, and once a princess of the Carian Royal family. While Rennala turned to scholarly magic and led the Academy of Raya Lucaria, Rellana walked the path of the sword. In the Shadow of the Erdtree expansion, players encounter her at the end of Castle Ensis, a beautifully gothic fortress nestled in the Lands of Shadow.
Rellana wields Twin Blades, which she can enchant with Glintstone sorcery and Messmer's Flame, creating a duel of magic and melee that is as stunning as it is deadly.
Where to Find Rellana
Rellana is the final boss of Castle Ensis, a location you'll naturally progress toward in the early-to-mid portion of the Shadow of the Erdtree DLC. The castle itself is filled with sorcerers, knights, and flame-infused enemies, teasing the hybrid fighting style that Rellana herself uses.
Before heading into the boss arena, make sure to rest at the Site of Grace outside her chamber, resupply on flasks, and review your build.
Rellana Boss Mechanics
Rellana fights in two distinct phases, each blending elegant swordsmanship with powerful elemental attacks.
Phase One: Swift Blades and Glintstone Magic
In this phase, Rellana uses quick slashes, magical projectiles, and sweeping AOE spells.
Watch out for her Glintstone Arc combos and Moonblade waves, which can strike from mid-range with little warning.
Phase Two: Twin Moon Infusion
At roughly 50% health, Rellana infuses one blade with Glintstone magic and the other with Messmer's Flame.
Her attacks become more aggressive, with lingering fire trails, explosive sword combos, and tracking moon spells that can wipe out careless players.
Recommended Elden Ring Items and Talismans
Success in this fight depends heavily on preparation. Bring the right Elden Ring Items to stay alive and deal consistent damage:
1. Magic Damage Resistance Gear
Equip armor with high Magic and Fire resistance, such as the Spellblade Set or Carian Knight Set.
2. Talismans
Spelldrake Talisman +2 – Greatly reduces magic damage.
Flamedrake Talisman +2 – Essential for surviving flame-enhanced attacks in phase two.
Radagon's Scarseal/Sourceal – Boosts Strength and physical damage for melee builds.
3. Consumables
Magicproof Dried Liver and Fireproof Dried Liver for elemental resistance.
Stanching Boluses to counter bleed buildup (some attacks may apply it via status).
Spirit Ashes and Allies
Summoning Spirit Ashes can turn the tide in your favor. These are ideal for this fight:
Mimic Tear Ashes – Mirrors your build, doubles damage potential.
Black Knife Tiche – Fast, agile, and applies consistent pressure.
Greatshield Soldier Ashes – Useful for tanking and drawing aggro while you flank.
Combat Strategy
General Tips
Rellana is fast and aggressive, but her moves are telegraphed with visual and audio cues.
Stay close to her in Phase One to bait melee combos you can dodge through.
In Phase Two, back off during blade infusion, then reposition carefully, her flame attacks cover more ground.
Phase One Strategy
Focus on dodging sideways from Glintstone projectiles.
Use jumping attacks or heavy strikes after her sweeping combos.
Fire-based weapons or bleed builds are especially effective.
Phase Two Strategy
Keep mobile, Rellana's flame sword leaves fiery trails that deal damage over time.
Dodge into her flame attacks rather than away to avoid getting clipped by wide arcs.
Save your Wondrous Physick for this phase to absorb burst damage or heal mid-fight.
Rewards
Defeating Rellana grants a wealth of Elden Ring Runes, which can be used to level up or purchase Elden Ring Items from merchants throughout the DLC.
Victory Rewards Include:
130,000–180,000 Elden Ring Runes (depending on NG+ cycle and Rune-boosting gear)
Remembrance of the Twin Moon Knight – Can be exchanged at Finger Reader Enia for either:
Rellana's Twin Moon (sorcery spell)
Rellana's Twinblades (dual swords with Glintstone + Flame scaling)
Access to deeper parts of the Lands of Shadow and potential hidden secrets in Castle Ensis.
Final Thoughts
Rellana, Twin Moon Knight is one of Elden Ring: Shadow of the Erdtree's most cinematic and punishing encounters. Her dual affinity with Glintstone sorcery and flame make her a hybrid threat unlike any other boss in the game. But with the right build, smart use of Elden Ring Items, and a steady stream of Elden Ring Runes, you can emerge victorious.
Take your time, learn her patterns, and enjoy the artistry of battle. Rellana may be optional, but for many players, she becomes a highlight of the DLC.
