kain saying only the reaver can kill him is enough, more than enough to show that it is, otherwise we are just assuming nonsense..no i dont have proof on him no being able to sacrifice himself, nobody in the world except the creators would know if kain can truly sacrifice himself. And no, Kain in water will destroy his body but he will only reform, or turn into thousands of bats like he does in-game, the only other considerance is that he is actually immune to water and does not know it, since he never is foolish enough to go into it, not to menstion he would never go into the water, what with mist form. Another thing is that if kain could be killed by normal means, then they would of done Yanos on him, moebius' staff works on kain when he has his heart just like any other vampire, if kain could be killed by water or being cut to pieces moebius could of done so easily, with a click of his fingers thousands of sarafan could come in and dice him, or drop him in the river if it was a true way of killing him.
spoiler sorry, dont know how to do that grey out thing
also no, ares is no way as large as quarter of a mile, hes perhaps twice as tall as the biggest building we see in greece. The reasoning is that mount olympus we see at the end with erhaps the whole titan army climbing up it is only 2 miles tall, we can plainly see that theres about 3 titans climbing it in the video, so they must be much smaller than people are overhyping them to be
and yes Kain can be Ko'ed, but the likelyness is incredibly low, considering he is harmed only by the reaver, he survives many slashes of the thing, having his soul draining little by little at the same time as it hitting his body, so his body alone must have incredibly endurance and then is blasted away by an incredible TK blast and hes knocked out for like an hour, maybe less....thing is kain has many ways to escape being hit, even if you dont believe he is very fast, he can instantly teleport and mist form IS mist, so cannot be hit when he does it...
