It has a special attack called From the Shadows: a wight is summoned from the Shadow Realm that attacks your target five times, dealing 20-100% ability damage each attack. This costs 50% adrenaline, and only one wight can be summoned at once. Weapon gizmos charged with perks can be used to enhance the weapon's abilities. As a two-handed item, the augmented Staff of Sliske can hold 2 gizmos, allowing up to 4 perks (2 perks each).
