Dark mind landscapes and only me...
Seas and rivers high,
Deeps and waterfalls...
Massive mountain, powerful mountain, still only me...
Where bergs and peaks throne,
Cold beneath... the MOON

I really like the idea of physical immune Spirits. As for the Spirit of Barbs issue, I recommend changing it to "Spirit of Plagues", have it poison everything in a certain radius at regular intervals (Or have the poison applied as the damage returned effect), have it stack with Rabies, and have it synergize with Rabies and Poison Creeper.
