So I played my first session of Grim World tonight.

So I played my first session of Grim World tonight. I love it, but it left me with a few questions about the Channeler class. I don’t quite get how the Summon Elemental works.  I’m unclear on what the Elemental Attack does when it embodies a tag.  Can it do damage itself if I give it blast or projectile?  Does it do no damage if I give it forceful?  How could it use barrier to give me +1 armor if I lose 1 control anytime it or I would take damage?  I feel like I’m missing something painfully obvious about this mechanic and I’d appreciate a bit of help.
