Arkain is rather surprised that his attack actually hit you. What he said about the spoils must have really distracted you. This is not what he wanted. Your eating him will help him reform much stronger. When he sees you still laying on the ground he wonders if he was wrong about you but then when you start to get up he can feel you as strong as ever. If you have a chance to look at the shoulder that was hit you will see that instead of being wet there is a rather thick gel on it that is not running off and the tree behind you that took the brunt of the attack is completely covered by the gel.<br/>When you get up Arkain quickly gets into a defensive stance. A grin still on his face. His expression quickly changes into shock when he sees the  giant snake come flying out of the sand. Definitely not the attack he was expecting. He quickly springs backward trying to stretch out towards the water hoping to fall into the water before the snake hits him. He tries to throw up a wall of gel to at least defect the attack but it turns out to be no more effect then him splashing water at it.
