Requirements and loadout
Long Sword needs 10 Strength and 10 Dexterity to wield one-handed. It weighs 3.0 units. Check your equipped load before changing weapons so you keep the roll you expect.
Where to find it
Knight starting weapon; sold by Greirat.
Infusion and field notes
Useful infusion: Heavy / Sharp / Chaos / Dark.
Raw can help early with low damage stats. Later, Chaos or Dark suits an Intelligence/Faith build; neither can be resin-buffed.
Infusion and damage depend on your current attributes and the enemy's defenses. Compare the result in your own inventory before spending upgrade materials.
