|The only biggest creature to live.|
JalTok-Jad is one of the monsters which can be found in the Inferno. It is a stronger version of TzTok-Jad, and similarly attacks in all three forms of combat where the player must use the appropriate protection prayers before the attack hits.
JalTok-Jads are encountered in the final waves of the Inferno, first appearing in wave 67. The JalTok-Jad encountered in this wave will have five Yt-HurKots healing it when it reaches half health. In wave 68, three JalTok-Jads will appear and attack the player. Each JalTok-Jad will only have three Yt-HurKots to heal it. JalTok-Jad can also appear in the fight against TzKal-Zuk on wave 69.
- Rather than having unique healers of their own, the healers for JalTok-Jad are Yt-HurKots, who also serve as TzTok-Jad's healers.
