Zuriel's staff

Zuriel's staff is a magic weapon exclusive to Deadman seasonals, requiring 78 Magic to wield. It is part of Zuriel's equipment, a set of Ancient Warriors' equipment, and is dropped by any monster found in the Wilderness as part of a global loot table, the chance being relative to the combat level of the monster.

Passive effect
The Zuriel's staff has a passive effect which boosts Ancient Magicks combat spells when equipped:
 * Ice spells - 10% increased accuracy.
 * Blood spells - Hitpoints restoration is increased by 50%.
 * Smoke spells - Poison damage is increased by 100%.
 * Shadow spells - Attack drain is increased by 100%.

Trivia

 * Ancient Warriors' equipment were originally added in a 2008, a year after the backup of Old School RuneScape.
 * Unlike its, it does not degrade. The original Zuriel's staff also functioned differently to the Old School RuneScape version - it did not have any passive effect, however it allowed the user to cast - a branch of spells on the Ancient Magicks spellbook that could only be cast with Zuriel's staff. Players affected by Miasmic spells had their Ranged and melee attack speeds temporarily halved, akin to Ice spells; the duration of this effect increased with the level of the spell.
