Moonlight Greatsword is a Weapon in Dark Souls. Moonlight Greatsword can be acquired by cutting off Seath the Scaleless' tail during the boss fight. While its attack type may suggest it only deals regular damage, it also inflicts significant magic damage. The weapon is particularly effective for Intelligence-based builds due to its high scaling with the Intelligence stat. One of its strong attacks releases a magic projectile that deals damage based on the wielder's Intelligence, making it a powerful choice for sorcerers. Greatswords are heavy, powerful weapons with long reach and wide swings capable of hitting multiple enemies at once. This power comes at the cost of speed, as they are slow to swing and require high stats to wield effectively. Their immense force can easily stagger foes, often creating openings for follow-up attacks.

This sword, one of the rare dragon weapons, came from the tail of Seath the Scaleless, the pale white dragon who betrayed his own."
"Seath is the grandfather of sorcery, and this sword is imbued with his magic, which shall be unleashed as a wave of moonlight."

Where to Find the Moonlight Greatsword in Dark Souls

Acquired by cutting off Seath the Scaleless' tail.
Out of the three tails, the player must cut the middle one by hitting the end of the tail until it comes off. Make sure you are lightweight enough to run quickly. Run over and stand by the crystal you need to destroy in order to damage the boss at the start of the fight, and wait for him to shuffle over and do a breath attack. Wait for his attack to end in a few seconds, then shatter the crystal which will stun him giving you plenty of time to chop or Soul Spear his tail off. The tail should fall off after about 500 damage.
After patch 1.05, the sword gets directly transferred into your inventory, so it is no longer possible to lose it for the playthrough, after cutting Seath's tail and leaving its tip containing the weapon inside the boss arena. You will acquire the weapon, even without finishing off Seath.

Moonlight Greatsword Hints and Tips in Dark Souls:

Can be wielded with 11 Strength with no penalties when two-handed.
Moonlight Greatsword can be upgraded by using Dragon Scales.
The Moonlight Great Sword's heavy attacks fling ethereal blades of magic at the enemy, which explode on impact. Each swing of this ability reduces durability of the weapon by 20-40 points, depending on whether you are wielding it one or two handed. These ranged heavy attacks have heavy knock-back, sending foes flying or knocking them down upon impact.
Wielding the sword raises Magic defense by 40.
The Intelligence damage scaling has greatly reduced effectiveness past 40 Intelligence. Up to and including 40 Intelligence, each point of Intelligence adds about 7 damage with a fully upgraded Moonlight Greatsword. Above 40 Intelligence, each point of Intelligence adds about 2 damage with the fully upgraded sword.
Pure magic damage, useful moveset and fairly low stat requirements make Moonlight Greatsword one of the most popular PvP weapons.
