Obsidian crossbow

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 only way to obtain the crossbow is to make it (Level 98 Fletching) with Obsidian Stock dropped from TzTok-Jad and attach them with an Obsidian Limbs which can be purchased from the shop for 500k Tokkul.

The crossbow has a special attack which is called Lava Strike which guarantees your bolt to use its special ability and also doing 25% increased damage and accuracy or your next two shots. The special attack (Lava Strike) has an animation which the bolts turn into the head of TzTok-Jad, this is similar to the Dark Bow special attack. This weapon only exists in Old School RuneScape because when the Evolution of Combat happened it was deleted from the game because it was too powerful and the special attack when taken out rendered the weapon weaker and Jagex decided to take it out because he had also decided to take out the spells Lava Surge and Obsidian Barrage, along with the Obsidian Godsword (made from TzTok-Jad's teeth). These weapons still exist in Old School RuneScape, along with the Void Cape (dropped by the Kraken). NOTE: Ava's Accumulator does not retrieve Obsidian Bolt Racks, but the Void Cape does.
