Elden Ring Guardian's Swordspear Notes & Tips

• Weapon Skill: Spinning Slash.
• This weapon can be infused with Ashes of War.
• Guardian's Swordspear can be upgraded by using Smithing Stones
• This weapons has massive scaling with Dexterity on the Keen affinity, so much so that a +25 Keen Swordspear will have higher AR at 99 Str/Dex than a +25 Quality Swordspear (813 vs 776 AR). Letter scaling continues to be misleading since it produces more AR with Dexterity on Keen (813) than than the two S-Scaling Halberds in the game do when they are used in one hand, those being heavy infused Gargoyle's Halberds(752) and Nightrider's Glaives(747) at 99 STR, they get more AR than Swordspear when two handed. 
• The Keen infusion on this weapon will also produce more AR than the Lightning infusion at 74 dexterity and above. The extra AR overshadows any possible benefits of having split damage on a weapon, even at low levels where split damage is less detrimental.
• Has a middling range compared to other halberds, being slightly above average length. 
• Has a unique moveset compared to other halberds, shared with the Loretta's War Sickle. Regular Light attacks (one-handed, two-handed and off-handed) are upward slashes, finished by a horizontal slice. Heavy attacks are the same as the default halberd moveset.  
• Dual wielding two of these does not provide a unique moveset. 
• Sell Value:  

   100

• Base drop rate is 2% (at 100 Discovery).
• NOTE: As of Patch 1.09, the scaling values of this weapon were changed. Please refer to the Upgrades Table of this weapon below.
