This page offers a guide on how to find all unique weapons in Nokron, Eternal City in Elden Ring.
|Gargoyle’s Greatsword||Dropped by Valiant Gargoyle in Siofra Aqueduct.|
|Gargoyle’s Twinblade||Dropped by Valiant Gargoyle (Twinblade) in Siofra Aqueduct.|
|Dragon Halberd||Dropped by Dragonkin Soldier in a secret area of Nokron, Eternal City that is only accessible via a teleport waygate on the eastern side of Siofra River region.|
|Winged Greathorn (from Remembrance of the Regal Ancestor)||Remembrance of the Regal Ancestor is dropped by Regal Ancestor Spirit in Hallowhorn Grounds.|
The Gargoyle’s Greatsword is wielded and then subsequently dropped by the Valiant Gargoyle found in Siofra Aqueduct. This is a dual boss fight so you’ll also be fighting Valiant Gargoyle (Twinblade) at the same time - he’ll drop the Gargoyle’s Twinblade.
Siofra Aqueduct is only accessible from Nokron and not Siofra River, hence why the area is considered a part of Nokron. To access it, you’ll need to do a bit of parkour. First, find the Aqueduct-facing Cliffs site of grace, which is located up the cliff north of Hallowhorn Grounds. Then, you’ll be able to jump down to the ruins below. You can then follow a relatively linear path down through a ruined hall area before you reach a fog gate that takes you into the boss arena.
The Dragon Halberd is dropped by the Dragonkin Soldier. The Dragonkin Soldier is found in a secret area of Nokron, Eternal City that is only accessible via a teleport waygate on the eastern side of Siofra River region (see map below). To reach the teleporter, travel up the large fallen stone column (watch out for the archers nearby!) and you’ll be able to find the waygate atop the ruins.
This can be obtained through defeating Regal Ancestor Spirit, who will drop Remembrance of the Regal Ancestor. You can then exchange the Remembrance of the Regal Ancestor for either a Winged Greathorn or an Ancestral Spirit’s Horn.
