User blog comment:Reece A Bowser/Gravelord Aldrich, Cleric of The Way of White/@comment-30629399-20181118010534

Aldrich's weapon is not a gravelord sword, actually. Its just Gwyndolin's stick. Aldrich just added an illusion of the Gravelord sword. If you've seen a picture of Aldrich before the boss battle, you can tell that he's only holding a stick. Some people have entered the arena prior to the fight using cheats, so thats how we know this.
