Lol. The thought of one-hit kills. Makes me think of Satan Morroc on a low rate I play. One skill, the whole screen is dead, and all the priests off screen rush to revive everybody, before he beats them to a pulp. Then the tanks are up again, then priests raise the priests, and the process restarts. :3
By the way, would the sprite matter so much, for it to look like a Ragnarok monster sprite, or could it be made in another style that still works in its animated way?
