The Inferno is a solo minigame in which the player must survive 69 increasingly challenging waves, ultimately killing the level 1400 TzKal-Zuk. If defeated, the player has to restart from the first wave. (premium players or players with a Zuk pet may pay tokkul to skip.) A spiritual successor to the TzHaar Fight Caves, the Inferno was dubbed the greatest solo PVM challenge to date upon release.

In order to access the Inferno, players must give TzHaar-Ket-Keh a fire cape. This is a one-time fee, so after giving a fire cape to him, TzHaar-Ket-Keh will allow players to enter as much as they want.

The Inferno can be reached by using the minigames teleport. The entrance is the large red portal or the NPC.

The Inferno is similar in nature to the Fight Caves, you fight waves of enemies that gradually get more difficult, ending in a final boss fight (which will still have some weaker enemy spawns at the same time.)

There are stronger versions of the Jad from the original Fight Caves, known as the JalTok-Jad, which could be seen as bosses. In one wave, 68, of The Inferno, you will have to fight three JalTok-Jad's at the same time.The final boss is “TzRek-Zuk”, level 1400.

• If players die within the inferno, they are placed outside the fighting area, and must restart either from the beginning, or the tokkul skip wave.
• Hardcore Ironman Mode players will not lose their status when dying in the Inferno, it is therefore a safe activity.
• Players WILL NOT get any Tokkul back from failed attempts
