N2 mage can forge Thistle Mace (Constr. 4 IIRC), which boosts him into N3. N3S1 allows for Moonvine Bracelet, so N4. N4 allows for Treelord's Staff, +2 N but it replaces Thistle Mace, so -> N5. Nature 5 already allows for Gift of Health, I think. Hmm. Check from someone that it works on inanimate beings (Oracles) first.

Faery Queen at high Conjuration is another possibility. Lamia Queens, also from Conjuration, will give you access to Death and Astral at least once you get lucky with one's randoms.
