you don't need the quest ring, just the rings in general are +10 hp. there are +20 rings around, too.
at rank 30 it gets fun, but you can do alright with a shifter with crap gear, then worry about it later. I've seen level 47 shifters with fine suits from the academy. powerranking mofos.
Let's see, gems in fires you can hold from near evermoon for some hp, snow worm gear, silver-gray junk laying on floor of high lords keep, captains hat in seantryn. earthen and arborian junk. Heh, just look at other shifters, and ask them where one or two items came from.
