The Greatsword of Radahn (Light) is a Colossal Sword in Elden Ring. It is part of the Shadow of the Erdtree expansion.

The Greatsword of Radahn (Light) is one of a pair of black steel greatswords decorated with a lion mane motif that Radahn wielded in his youth, held just before his triumph over the stars, swords of a lord who did not rely on physical strength and gravity alone. It is one of the options when trading the Remembrance of a God and a Lord with Enia at the Roundtable Hold. It is a paired weapon, so two-handing equips a duplicate in the off-hand, and its powerstanced moveset hits hard against large, immobile bosses but struggles against mobile enemies. It scales with Strength and Dexterity at D and Intelligence at E, and its unique skill, Lightspeed Slash, has to be charged while standing still for full damage.

Skill

---

Lightspeed Slash costs 26 FP. The wielder takes on a luminous form and leaps forward in a downward slash at the speed of light, and pillars of light then burst at the point of impact. Charging the skill raises the power of the slash and adds more follow-up light. The light deals holy damage that scales with Intelligence, and the Godfrey Icon boosts the charged version. No other weapon carries this skill, and it cannot be replaced.

"Assume a luminous form and leap forward to deliver a downward slash at the speed of light. This attack will be followed up by an additional light attack. Charge to increase power of the skill and number of follow-up attacks."

Suggested Build

---

Stats	Strength 60, Dexterity 40, Intelligence 36 for gravity sorceries, Vigor 60, Mind 20, Endurance 47
Affinity	Cannot be infused; it keeps its own scaling.
Talismans	Carian Filigreed Crest, Shard of Alexander, Dragoncrest Greatshield Talisman, Graven-Mass Talisman
Pairs With	Meteorite Staff, Opaline Hardtear, Greenburst Crystal Tear
