Hidden Weapon is a Sorcery in Dark Souls 2. To cast a Sorcery, you must use a Staff or Special Weapons that can cast Sorcery.
"A sorcery that dates farther back than recollection. Makes weapon in other hand invisible.
Effective use of this, like any tool, perhaps, is reliant upon the ingenuity of its caster."
- Achieving the second rank in the Bell Keepers Covenant and speaking to the covenant leader.
- Makes weapon invisible; effect ends if weapon is switched.
Best used out of sight of opponents.
Count as a weapon buff (like Crystal Weapon) and as such cannot stack with other weapon buffs.
Lasts 90 seconds. (affected by Lingering Dragoncrest Ring as well)
Extremely useful if paired with Blue Flame, it creates an illusion of one casting spell with barehands.
