Sometimes the arrow strays slightly to the right or left, and for the wide stance animation, the blasts stray to either side of the target.
I’m guessing this is because the arrows/blasts aren’t being casted from the centre of your character, such that when you aim at your opponent, you are actually aiming at the solid object behind them. The bow casting animation causes the arrow to cast a few degrees to the left of the player.
the blasts come out of your magic circles, and in the wide stance animations the magic circles aren’t in the middle of your character, ontop of that there’s 2 of them.
so unless you’re firing a single blast, they will spawn from your hands
Save all multi circles for high levels. Once your magic’s size gets larger, targets won’t be able to move in between, and it will widen the radius of barrage attacks, effectively making them larger.
