Carian Knight's Sword is a Straight Sword in Elden Ring. The Carian Knight's Sword scales primarily with Intelligence, Strength and Dexterity and is a good Weapon for dealing Magic Damage from the sorcerous battle skills that it wields. 

Elden Ring Carian Knight's Sword Notes & Tips

• This weapon has a unique heavy attack that can block attacks before its slash comes out. Charging the heavy attack will further extend the time the weapon can block before slashing. Unfortunately, this attack does not work with the Curved Sword talisman. (Only this sword and the Lazuli Glintstone Sword have this move).
• Blocking any attack with this weapon's heavy attack will never put you into stun, unless the move you have blocked completely drains your stamina. 
• After brief testing with the spectral version of the Troll Knight below The Four Belfries, 2-handing this weapon will increase this weapon's guard boost by 10%, just like any other weapon. This does include this weapon's heavy attack and this does stack with the Greatshield Talisman.
• Weapon Skill: Carian Grandeur.
• This weapon cannot be infused with Ashes of War.
• Can't be enchanted with Magic nor boosted by Consumables.
• Carian Knight's Sword can be upgraded by using Somber Smithing Stones.
• Sell Value:  

   200 Runes.
