The two-handed Zamorakian Spear, upon examination, is described as “an evil spear.” This was likely written by someone or something that had the unfortunate experience of getting poked by it.
The Z Spear is a ferocious weapon, boasting high defense and attack speed stats coupled with the versatility to stab, crush, or slash enemies. On the stabbing note, it is the stabbiest weapon in the game with a stab bonus of +94. Deadly effective at dispatching Corporeal Beasts.
Getting this spear requires a lucky drop in the God Wars Dungeon from defeating K’ril Tsutsaroth and his bodyguards. With an attack of 70 or above, this mighty weapon is immediately available for service to the victorious warrior.
Also, worth mentioning, this weapon can be converted into an even more formidable one-handed Zamorakian Hasta by paying Otto Godspeed 300,000 coins. This weapon has all the same stats, but because it is a one handed weapon you can equip a shield or defender in the off hand.
