• Enduring RotationWeapon

  Rolling Cutter grants 2s Endure after Release. Rolling Cutter damage +5~30%. Special Skill Rolling Cutter Fan damage type changed to melee PDMG, but damage -25~42%Not available in SEA yet (a level 90 system). It would fit this build well: 2 s Endure plus +30% Rolling Cutter damage, though the Fan of Knives would become melee damage at -25%.

• Rolling Cutter's base hit is melee damage, but Spinning Fan of Knives is ranged; melee cards are the safe choice since mixing in ranged cards is untested.
• On a low budget, dual daggers can out-damage Katars in dummy testing, so consider that route if gearing a Katar is too expensive.
• At level 80 the General set (Assaulter Plate, Captain's Manteau, Battle Greave) adds PDMG +2% per piece plus a set bonus.
