Noxious staff

The Noxious staff is a level 90 two-handed Magic weapon made by combining a spider leg with Araxxi's eye at level 90 crafting. Players may obtain the pieces needed for the staff by killing Araxxor. This weapon is currently the most powerful 2-handed Magic weapon outside of Daemonheim, and lasts for 10 hours of combat before degrading into an unusable state. Repairing it from a fully degraded state will cost at Bob's Axes, or less at a player-owned house armour stand, depending on the player's Smithing level.

Special Attack
The Noxious staff has a special attack named Mirrorback, which requires full adrenaline or special attack and will summon a mirrorback spider to aid the player. While active, the spider will reduce damage from attacks against the player by 50%, and reflect that damage to the attacker, but the spider will also be damaged for an equal amount. For instance, if the player is hit by an attack that deals 1000 damage, both the player and the spider take 500 damage, and the attacker receives 500 points of deflection damage. This will last for ten seconds or until the spider is killed. This special attack does not deflect damage from certain attacks, and also cannot deflect damage back to attackers that are immune to deflection damage, such as the Queen Black Dragon.
