In the ever-expansive world of Elden Ring: Shadow of the Erdtree, the Obsidian Lamina stands out as one of the most coveted weapons. This unique scythe, wielded by the formidable Pureblood Knight Sir Ansbach, combines elegance with lethality, making it a must-have for players. This guide will walk you through the steps to obtain this weapon and provide a detailed overview of its attributes and capabilities.

Overview of the Obsidian Lamina
The Obsidian Lamina is not just any weapon; it’s a signature scythe that epitomizes the combat prowess of Sir Ansbach. This reaper-type weapon specializes in Slash attacks, all dealing pure Physical damage. The weapon’s edge, crafted from obsidian, is designed for those who rely on skill rather than trickery. It leaves a trail of blood in its wake, fitting for its association with Mohg, Lord of Blood. With a blood-loss buildup rate of 59, this scythe surpasses other Reaper weapons in its category.
Weighing in at a mere 6.5, the Obsidian Lamina is perfect for players who prefer agility and speed in combat. Its unique skill, Dynastic Sickleplay, enhances its evasive nature, making it ideal for those who favor blood-based incantations.
Stat Requirements and Scaling
To wield the Obsidian Lamina effectively, players need to meet the following stat requirements:
- Strength (STR): 12
- Dexterity (DEX): 25
- Arcane (ARC): 17
When upgraded to +10 using Somber Smithing Stones, the Obsidian Lamina’s scaling improves as follows:
- Strength: E to E
- Dexterity: C to B
- Arcane: D to D
Dynastic Sickleplay: The Unique Weapon Skill
The Obsidian Lamina’s Ash of War, Dynastic Sickleplay, cannot be swapped out for another skill. This unique ability allows for an evasive maneuver, creating space between the player and their foe. The skill costs 7 FP to cast and can be followed by two additional strong attacks, each costing 9 FP. The first follow-up involves an advancing upward slash, and the second brings the weapon back down for a powerful hit.
