Crystal Greatsword is a Weapon in Dark Souls and Dark Souls Remastered. Crystal Greatsword is a high-power but brittle crystalline greatsword that cannot be repaired or upgraded. 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.

A fully crystallized greatsword. How such a weapon was created is entirely unknown.
The crystallization boosts its attack, but makes the blade brittle. The sword cannot be used for long, as it cannot be repaired."

Dark Souls and Dark Souls Remastered Crystal Greatsword Hints and Tips:xxx

Can be given to Kingseeker Frampt to receive 1 Soul.
Like all Crystal weapons and armor, cannot be upgraded or repaired.
Quite a useful weapon for new players going through the Depths and beyond. It has more durability than regular Crystal weapons and its AR and moveset is roughly the same as a Bastard Sword at +8. Buying one to use solely for bosses can make Gaping Dragon and Chaos Witch Quelaag, and even the Iron Golem for Dexterity focused characters, much easier to solo.
Be wary when seeing this weapon in PvP, for it is rarely actually used. Instead, it is most likely a hacked version that does ~1100 damage while in one hand. This weapon is especially deadly since, being a greatsword, it can easily break your poise and drain your stamina if you are trying to block its swings.
