Noxious longbow

The noxious longbow is a level 90 two-handed Ranged weapon made by combining a spider leg with Araxxi's web. Players may obtain the pieces needed for the longbow by killing Araxxor. The Noxious Longbow can only fire Araxyte arrows, which are dropped by Araxxi as a 100% drop. This weapon lasts for ten 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 longbow has a special attack named Mirrorback, which requires full adrenaline 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 it 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 work against certain attacks, and also cannot deflect damage back to attackers that are immune to deflection damage.
