Tokkul

Tokkul is the only currency of the TzHaar people residing in the underground TzHaar City. It is made from obsidian, a volcanic glass; it cannot be created by players. Tokkul is sometimes referred to as TokKul by some of the NPCs in the city. Apparently, Tokkul is made out of corpses of the TzHaar, as said in a Postbag from the Hedge letter, which is why players cannot trade Tokkul with other players.

According to the Wise Old Man in Postbag from the Hedge 12 and 14, the name TokKul means, roughly, rock token or material value.

Getting Tokkul
Since Tokkul isn’t tradeable, it is difficult to get. There are currently only five ways to get Tokkul:
 * competing in the TzHaar Fight Pit
 * competing in the TzHaar Fight Cave
 * selling items in the TzHaar Shops (the mining areas in TzHaar would be useful for their ores or gems, if a player has mining level of 20+ for silver; level 40 is required to mine gold)
 * killing the TzHaar citizens and guards

TzHaar Fight Pit
The TzHaar Fight Pit minigame, along with selling to the TzHaar shops, was the first way to get tokkul. Tokkul is only received from the fight pits if you are its champion. The amount of Tokkul you receive as a reward is based on how many participants are in that round.

TzHaar Fight Cave
The Fight Cave is the ultimate gauntlet for players proving themselves worthy of a Fire Cape. Players obtain variable amounts of Tokkul as a consolation prize depending on how far they progress before succumbing. If a player completes the Fight Cave, they will receive 16,064 Tokkul along with a Fire Cape.

Selling Items
This is a way to get quick Tokkul at low levels. It is mainly most effective to sell runes at the TzHaar Rune shop, obsidian mauls, or ores and uncut gems at the gem shop. The TzHaar stores buy back items for approximately 10-20% of the store selling price. Due to the limited usefulness of some of the Tzhaar weapons (maul, knives, sword), the price of these items are determined by the price of the Onyx gemstone.

Note: The Tzhaar shops no longer pay more if a player is wearing the Karamja gloves 1 after the Personalised Shops update.

Buying And Selling Items

This way to get Tokkul is long, but easy. If you're able to teleport to Varrock you can just buy runes there. Then go back to Tzhaar and sell the runes to the rune seller in Tzhaar.

Spending Tokkul
After a player earns a good amount of Tokkul, they have three places to spend it in.

Note: The Tzhaar shops no longer offer a discount if a player is wearing the Karamja gloves 1 after the Personalised Shops update.

TzHaar-Hur-Lek's Ore and Gem Store
Note: prices without an alternate selling price listed are only the starting shop prices, these prices will likely drop dramatically as you sell more to the shop. onyx bolt tips add 1 each one you buy. A recent update has dramatically increased the prices of all these items.

Trivia
US$
 * TokKul is spelt 'Tokkul', when in your inventory. But when you attempt to value something at a Tzhaar store it reads 'TokKul'. It is unknown whether this is an error in the coding of the game or there purposely.
 * With the personalised shop update, the price of the uncut onyx gem was increased by roughly a factor of 10. The buying and selling prices of other items were also somewhat increased, thus devaluating the Tokkul currency. This angered some players who were saving up to buy an onyx gem, and had therefore invested substantial funds in Tokkul.
