I was just wondering. Arkadius Combat Syringe is a Magical Weapon. The weapon also states that it cannot hurt non-living models since it is a Needle. I know that I am new to the game, but what do we have out there that is living and only can be hurt by magical weapons?
EDIT: I guess that it would be possible to hurt something with Brain Damage (since it theoretically could affect non-living targets) and Arkadius strength of 4 and thus get the Brain Damage effect, but when I started editing this post I saw that when you use the Combat Syringe you never even roll to resolve attacks with a Needle. So I guess I could hit a construct or undead model with the Syringe, hoping to use Brain Damage since it doesn't need the target to be living, but it wouldn't work since the Needle rule says that you don't resolve the attack.
