The ice griffin had its entire left side cut open causing its partially raised body to tilt to the left as its hind leg buckled, unable to maintain its current stance.
Frost's manoeuvre took care of one talon strike and severely diminished the amount of strength the griffin could bring down upon Kiba, but the remaining right forelimb was still poised to descend. Even with his actions if the griffin got hold of Kiba with just one talon the damage could prove devasting. Though Kiba's ribcage wasn't a major weak point like with wolves it certainly wasn't a match for the hardest part of the ice griffin. The mangled corpse of the Baltic tiger was proof of that.
"Shit!" Frost didn't have enough time to place himself in front of Kiba to block the strike and the big tiger was too heavy for him to kick away.
