[GAMEPLAY] Lightslinger "killing" Voidlings

I have been playing Lucian a lot recently, and playing against Malzahar's a lot recently. One time i wanted to kill a Voidling faster, so i tried to use Relentless Pursuit to get a Lightslinger proc on it, but it only attacked the Voidling once, and the second shot hit a minion. Later on, i tried it again, except there were no minions nearby, and both shots hit the Voidling for full damage.

1. Have a Malzahar spawn a Voidling.
2. Try to use Lightslinger on it near minions.
3. Lucian will attack the Voidling once, then a minion.
