Staff of the dead

The staff of the dead is a one-handed staff that requires 75 Magic and 75 Attack to wield. It is dropped by K'ril Tsutsaroth. It has a 1/512 chance of dropping it, much like the majority of God Wars Dungeon items. It is also recommended to use The staff of the dead if doing high level (Bolt/Blast/Wave) spells, over the Smoke Battlestaff, especially when splashing as the 1/8 cast saves will greatly overcompensate the loss of air and fire runes. The staff of the dead is the only weapon in the game that offers a special attack gives opponents a disadvantage, rather than just giving the wielder an advantage/more damage.

The staff of the dead features a number of properties that are very useful to mages:
 * The Flames of Zamorak can be autocast using this staff
 * The Slayer Dart spell can be cast using this staff.
 * All of the normal spellbook's damaging spells can be autocast using this staff.
 * This staff has the third highest right-hand-slot magic bonuses, behind the Master wand (at 20) as well as the Third Age Wand.
 * Magic damage is boosted by 15%.
 * The staff has a special attack that halves all melee damage of your opponent(s) (all opponents that hit you in the time of the special attack are lowered.) for one minute at a cost of 100% special attack energy. This effect stacks with the PvP damage reduction effect of the Protect from Melee prayer.
 * When a combat spell is cast with the staff, there is a 1/8 (12.5%) chance that the staff will negate the rune cost for that spell.
