Its a HP based attack and removes all buffs. To make this really simple for you, when it goes below 55% HP it will use "Open Mouth", then you guard all of your units. Next turn it uses "Withering World" that removes any buffs and does 170% damage, but because you gaurded it does about 80-85% and you live. It uses Open mouth randomly after that and will use Withering world the turn after, so as long as you pay attention to when it uses its attacks and guard you'll be fine.
