Problem with arrow ability

[zedak]

I need help with making a spell, it should be a self-aiming arrow that only can hit 1 target.

Example: Miranas Arrow, but I don't need the "stun" effect.

I've tried to use shockwave and changed the missile art, but it results in an arrow placed on the ground, instead of shooting away. Please help me

Here's a really basic sliding spell.

I think it's basically what you are looking for except maybe you don't want the units that are hit to explode into giblets. That's easily edited though
