##Yes, the Barbarian can benefit from his/her own Spirit Shield##

Even though Spirit Shield is an ability not a spell, the rules on spell casting talk about situations where a (spell) effect creates similar targeting situations:

> **Targeting Yourself**

> If a spell targets a creature of your choice, you can choose yourself, unless the creature must be hostile or specifically a creature other than you. If you are in the area of effect of a spell you cast, you can target yourself.

Because the Barbarian can see himself, he can target himself to benefit from Spirit Shield. Of course, the flipside of this is that Spirit Shield would not be available for use on an ally until the next turn, so doing this *does* have an opportunity cost.
