I read the unofficial iron defender page from 2011, but it may be dated and all is not clear. I'm wondering what I can do to beef it up. Survivability is top priority. I gave it a basic lvl32 docent with one blue augment for now. What augments are actually useful? Finding a collar is going to be more work, but I will get to that. I gave it the self heal enhancement which also helps my character. Im a warforged artificer and I dont want to have to constantly waste spell points taken care of his sorry hind end.
