So far, all I really have are Elans with Heart of Steel, Flexibile Spine, maybe a Telekenesis Eye, Antennae, Climbing Legs, Healing Blood, Silthilar Bones, Silthilar Muscles, Silthilar Tendons, and a full suite of Inherent bonuses. I don't think I really like the 'new style' grafts, they all require a very large sacrifice, and don't improve the quality of life... and I am totally assuming here that, as a god, you can get past the gp cost and the 'donor' issue... I only really see Heart of Steel (being immune to disease and poison is a big deal, greatly improving potential quality of life... and the fact that the society will have large scale access to Cure Moderate Wounds as a level 1 spell mitigates the healing issue...)
That's... pretty good, I suppose. Any more thoughts?
