Kill them quickly, we need to regenerate mana.

By the way, you have 495/510, I forgot about the second part of the passive ability again.

Can't we turn around now?

You can, but then you'll hit the reef with your side.

Antaer can't reach those lower sirens anymore, right?

He can't.

Can we hit two targets per turn?

Actually, no, but as an exception, you can attack a target standing next to you (within attack range) if the original target dies.

Can we attack diagonally?

Yes.
