-First aid over medicine. My first aid is 6 with a specialty and my medicine is 1 (maybe a little too low, but skill points were tight). I call myself a paramedic and tell them that surgery and long-term care aren't my specialty. I rarely miss the points in medicine (and wish for more in first aid)
I had the idea that my character volunteered at retirement homes, and has a bit more familiarity with extended care and surgery. Hence, the high rating. I think I might dial it back and take the Extended Care specialization. It makes sense...unless I change his story a bit.
-Spirits. your initial concept had a specialty in earth. I find that I rarely use the earth spirits - only when I need (literally) heavy-duty lifting. If you want it for combat I suggest an air spirit. They are fast and agile where the earth spirit is clumsy. Throw the optional Energy aura and they are great in melee; or Energy attack to be great at range.
The only reason I chose Earth is because it's the Spirit, in the Shamanic Tradition, associated with Health spells. An Aspected Conjurer can't cast spells, but I thought it would be interesting if the Spirits respected his role as a "medicine man" and were helpful because of his connection to "health." If I were to choose the Hermetic tradition, the "health" equivalent would be the Spirit of Man, which has more of Powers making them more versatile. Still, I prefer the Shamanic tradition as they treat Spirits more like peers and/or respected elders, rather than subjects with the Hermetic tradition. Maybe I could play a Hermetic mage who's NICE to Spirits...
-That high willpower is nice for full defense. Not uncommon for me to dispatch a spirit then go full defense (then spend an edge).
I think you will have a great time with the character and be a valuable member of the team.
I know it is early, but you might get a lot out of the channeling metamagic when you save up enough karma to initiate. If you are willing to plan that far ahead you can 'channel' a spirit to get unarmed combat - allowing you to save a few points on that at creation.
Have fun
Thanks for the advice! I'll be posting more of my character shortly....I hope.
