The pebble is sinking.
/ Well, maybe, Ney... But I wrote this when I didn't quite understand the essence of the pool. It's probably deep... I don't really want to swim in it. And then there's the question of how to break the distant spheres. But they need to be broken, I'm almost sure. Maybe I can use magic, but if they absorb it... I could risk it and, by swimming, break the distant spheres. Then we'll break the one near the entrance. Maybe the pool will then drain, or a bridge will appear to get to the central sphere. Or nothing will drain, but the spheres need to be broken in any case to win, and the point of the room is that the boss is difficult to reach with melee attacks because of his location in the middle of the pool. /
