The Tz-Kek is a level 45 monster found in the TzHaar Fight Pits and Fight Caves. It resembles a roughly man-high, amorphous blob of lava.

While rather weak, the Tz-Kek has a mechanic similar to the Ring of recoil; if attacked with melee, it will reflect 1 point of damage (regardless of the damage inflicted) back at whoever damaged it. Upon death, it splits into two level 22 Tz-Keks, which are weaker and lacks the recoil mechanic.
