Why do anything to the priest before he is our follower? Once he is our follower, it should be easier to work on his body, and he should consider it a blessing rather than a curse.
Hmmm...Yes, let's spend mana on that first...
Grow the thornbushes and roses to create a hedge wall of thorns and flowers. Chaos will be used to infuse it with a rudimentary intelligence, and make it harder to circumvent; no patterns in the design, save being 8 feet tall, 2 feet thick, extremely hard and thorny, and covered with flowers. Use Fire and Life to make Blaze-Blossoms(or some other, better name); the flowers will get a parabolic shape, and become highly reflective; they can reflect the light of the sun to burn enemies. A single one does no more than warm you, but when there are seventy...They will not attack neutral or friendly forces to my name; indeed, they will only attack that which disturbs them, meaning anyone trying to get through the Wall from the outside.(Goddamn teenagers are sure to try and climb it at some point) As well, some of the flowers, at the top of the wall, will grow higher and thinner, creating a shape remniscent of a lightning rod; but these do not only absorb lightning, they use it's heat, and the heat of the sun/heat the plant produces as part of it's metabolism(still has leaves, after all), to create firebolts.
That's two of his three domains hopefully circumvented...can't really do anything about the crafting one.
If we have mana left, should we talk to the priest?
