[ArM5] Unfamiliar Familiar Techniques

[robertrodger at earthlink.net]

We decided to be very generous when it came to familiars. Anything with a Might is pretty much fair game (although that may be restricted to Magic or Fairy Might). 

My Herbam specialist has decided to take a magic walnut tree as a familiar. (What? One of our vis sources are golden walnuts. He planted one. It's growing.)

When he's ready to bind his familiar (after making sure it's willing to become one) what would be an appropriate technique to use? Clearly, herbam will be the form.

Creo makes a little sense in the whole seed, growing, cycle of life-tree sort of thing. But is there anything else? Anything that seems even more appropriate?
