Watchdog's Greatsword Colossal Sword

Lore

Stone greatsword wielded by Erdtree Burial Watchdogs.

Though decorated with the watchman’s eye, the pupil was taken by graverobbers and is now hollow, leaving this sword a mere lump of stone.

The Watchdog’s Greatsword scales with Strength and to a lesser extent Dexterity and is a good Weapon for cleaving multiple enemies at once.

In the Giant’s Mountaintop Catacombs dungeon. This dungeon is located East past the Zamor Ruins grace. When the fire enemies first come into sight, peer over the right edge and there will be a place to drop down to enter the dungeon. Once you enter the dungeon, you will eventually come across a lift. Take the lift down, and then trigger the lift but quickly get off. Another lift will rise up from underneath and by taking that new lift down, you will enter the area with Two Watchdogs as well as other various enemies. The second Watchdog can drop it.
The sword wielding Watchdog enemy in the Consecrated Snowfield Catacombs can also drop this weapon.
