Turrets will neither receive ricochet from damaging a nearby unit, nor will hitting a turret ricochet to another target.

Turret deals spirit damage, and isn't effected by weapon upgrades

I'm not talking about turrets gaining the benefits from ricochet, my post is referring to a player on the opposite team shooting at a McGinnis turret or shooting at a unit near a McGinnis turret while that player has ricochet.
