Obsidian Crossbow (Tek-Torktz-Kuvzc) is the highest level crossbow in Runescape (level 98 Ranged) wielded in both hands. It is a repeating crossbow similar to the Karil's crossbow, so it fires Obsidian bolt racks which can be made using 1 onyx. Only one rack is needed as the crossbow shoots bolts not Obsidian bolt racks. The bolts are only obtainable by killing TzHaar creatures or buying them from the store. The bolts can be tipped with Onyx bolt tips (Level 98 Fletching) and enchanted (Level 98 Magic) to create Onyx Bolt (e) which then can be put in the Obsidian bolt rack. The bolts have a special ability similar to the Dragon bolt (e) and Emerald bolt (e) it does lava damage which at first does 25, then after 2 ticks does 20 damage and after 3 ticks does 15 then 4 ticks does 10 etc. The
