Godskin Peeler is a Twinblade in Elden Ring. The Godskin Peeler scales primarily with Strength and Dexterity and is a good Weapon for melee users but requires a high dexterity character. 

Elden Ring Godskin Peeler Notes & Tips

• Weapon Skill: Black Flame Tornado
• This weapon can be infused with Ashes of War and buffed with magic
• Godskin Peeler can be upgraded by using Smithing Stones
• This weapon has a unique R2 and running R2 that utilize the winding spike end.
• Sell value: 

   500 Runes.

• At +25 with Blood affinity and at 40 Arcane, the bleed build-up per hit is more than 120. In NG+ if you obtain it a second time and upgrade that one as well to +25 Blood and dual-wield them, a jumping attack will hit 4x, applying a whopping 480 bleed build-up per jumping attack. This will trivialize any boss not immune to bleed even in NG+ and beyond. In 1.09 this will do about 200 bleed, which is still good, but nerfed significantly. A full 2H charged R2 combo will do 300 bleed, if you can get it off.
• A good alternative to the above-mentioned strategy in NG (since you can only get one Godskin Peeler per NG-cycle) is a Blood Godskin Peeler and Eleonora's Poleblade, dual-wielded, fully upgraded.
• For a crazy amount of physical damage plus bleed buildup on an arcane build, infuse it with Sepukku aow and convert to to an Occult weapon. Then pair it with a bleed infused Twinblade on your offhand.
• NOTE: As of Patch 1.08, the speed of some attacks has been increased and the recovery time has been reduced.
• NOTE: As of Patch 1.09, the scaling values of this weapon were changed. Please refer to the Upgrades Table of this weapon below.
