Vezon - Kardas weakness

Kongu took advantage of Vezon’s boasting to aim and fire an energy bolt. The shaft stung Kardas, who evidently did not share Fenrakk’s ability to absorb the force of the blow. The Rahi responded with a blast of its own, which drove Kongu over the lava channel and into a stone wall. The rock shattered at the impact of his body and the Toa of Air found himself falling through into another chamber.

“Good Kardas,” Vezon cooed, patting his mount on the back of the neck. “Nice devastating monster. Are you my favorite engine of destruction? Yes, you are.” He looked back at the shaken Toa. “Energy — Kardas produces it nonstop. So it’s either release it by blasting you, or else go boom himself. Which did you think we would choose?”
