Requirements and loadout
Fume Ultra Greatsword needs 50 Strength and 10 Dexterity to wield one-handed. It weighs 25.5 units. Check your equipped load before changing weapons so you keep the roll you expect.
Where to find it
Dropped by Knight Slayer Tsorig in Smouldering Lake.
Infusion and field notes
Useful infusion: Cannot be infused.
Two-handing helps meet the Strength requirement, but does not reduce equipment weight. Recheck your roll before the next fight.
Infusion and damage depend on your current attributes and the enemy's defenses. Compare the result in your own inventory before spending upgrade materials.
