- Sold by Big Hat Logan in The Duke's Archives after he has been freed the second time, for 20,000 souls.
This spell applies Magic Damage to the equipped melee weapon by 1.4x the magic adjust of the equipped catalyst and lasts for a duration of one minute. As with other sorcery-based weapon buffs, Crystal Magic Weapon does not receive damage benefits from the Bellowing Dragoncrest Ring, but does receive duration-lengthening benefits of the Lingering Dragoncrest Ring.
As the buff reaches closer to the end of its duration, the number of crystal present on the weapon diminishes. When all the crystals have disappeared the buff expires.
While Crystal Magic Weapon is not as strong as the miracle-based weapon buffs Darkmoon Blade and Sunlight Blade, it does hold several key advantages over them. It has a lower intelligence requirement than the faith requirement for either Darkmoon Blade or Sunlight Blade, and it has more casts than either of them. Finally, while Crystal Magic Weapon benefits from the Lingering Dragoncrest Ring, Darkmoon Blade and Sunlight Blade do not.
While Darkmoon Blade and Sunlight Blade scale better with a Talisman's magic adjust, the Tin Crystallization Catalyst is able to provide higher magic adjust than any other talisman, making the Crystal Magic Weapon comparatively more powerful for the same amount of casts.
