Found in Farron Keep, down the path from the Farron Keep Perimeter bonfire, past the Ravenous Crystal Lizard and near the shortcut gate back to the Crucifixion Woods.
Reinforces right-hand weapon with Magic, adding 85% of the catalyst's Spell Buff as Magic damage for 60 seconds. The duration of the buff can be extended by equipping the Lingering Dragoncrest Ring.
For catalysts that scale with both Intelligence and Faith, only the Intelligence portion of the Spell Buff is counted. Special catalysts such as the Archdeacon's Great Staff and Man-grub's Staff are treated as having the base 100 Spell Buff.
