The Tsunami of Vital Ruin was a truly savage and torturous ability. At its core lay a heavy reliance on the Law of Life, generating that unstable infusion of life force that ravaged opponents from the inside.
The key to resisting it—if one existed—was to somehow wrest control of the chaotic life force before it shredded one's body. Of course, that was far easier said than done. The most straightforward method would be to surpass the Law of Life control wielded by the caster, but Cain had no hope of outmatching a Third Realm master in that domain. The alternative might be to cancel the Law of Life with the Law of Death, but that, too, was beyond his current abilities.
However, there existed a third path. It was a long shot, the odds of success practically nonexistent, but at this desperate moment, it was the only option Cain had. So he rolled the dice.
