I can tell you that the Onyx Lord's Greatsword is one of those weapons that feels heavier in your hands than it looks. From what I've gathered in the community and my own experience, it weighs 11.5 units in-game. That might not sound like much, but when you're mid-roll trying to dodge Malenia's Waterfowl Dance, every decimal point counts. The heft is part of its charm though—it swings with a satisfying weight that makes each hit feel impactful. Compared to other colossal swords like the 'Guts' Greatsword', it's slightly lighter, which gives it a nice balance between power and mobility. If you're building a strength-focused character, this is a fantastic choice for its unique moveset and aesthetic.
What's really interesting is how the weight affects gameplay. At 11.5, it's just heavy enough to require careful stamina management, especially in PvP. I've seen players pair it with the 'Great-Jar's Arsenal' talisman to offset the load, and the results are brutal. The weapon art, 'Onyx Lord's Repulsion', adds another layer of strategy—timing it right can turn the tide of battle. Whether you're a lore enthusiast drawn to its connection with the Onyx Lords or a min-maxer appreciating its scaling, this greatsword is a heavyweight in more ways than one.
