I'm going to be very spellcastery, so no, I won't be making tons of attacks. I do intend to take care of party healing. For a feat I can get an aura of fast healing 1 (all the way up to full, unlike many similar auras), and at least one of my formula choices can do Devoted Spirit-like healing.
Edit: Bah, accidentally hit post before I was finished.
Definitely get Ætherbeast. Astral constructs are great. Not the least of which, give them Improved Bull Rush from menu A and they're like an Æther Push with only a slightly lower modifier (+2, or +4 on a charge) that doesn't need a touch attack and also sticks around for a couple of rounds to keep bull rushing or hitting things.
OK so I can definitely rock Force Æther, even with a nerf to that healing aura. That'll make Persistent Ætherbeasts a thing.
Garryl, you have a lot of direct damage and a fair amount of buffs, SoD, and a bit of BFC. I think I actually am going to take Ætherfire Aura, since it's not limited to melee attacks, so it can buff your spellshape attacks, too. And I can throw it on our Ætherbeast of burden.
Æther Probe seems like a good idea, unless I'm missing something and someone else has detect magic.
So the current list is: buff AC, minions, bonus damage, and detect magic.
That leaves room for one more, my options are: buff saves, buff base speed, ranged bull rush, ranged attack (not worth it IMO), or weapon of æther. Thoughts?
