I take it he will approach but not expose himself to the direct line?
If you want to strike along the line, you can choose your own position. Magic on horseback can be combined with movement. But unlike Zidil, he will shoot back in response, because you won't be able to get more than 12 tiles away along the line. He moves 7 tiles, and no matter how you move to the edge of the arena, it will be less than 12 tiles.

Если где-то чего-то убудет, то в другом месте добавится.
