i'll use the snake shaman as an example - it says that the snake gets +2 dice for any one spirit of the land (shaman's choice) as a wilderness totem. as an urban totem, you get +2 dice for any one spirit of man (shaman's choice).
my 2 questions:
1) do you choose whether it's a wilderness totem or an urban totem at character creation, or can you choose which you are over and over again during play, based on which suits you best at the moment.
2) same for the 'any one spirit of...(shaman's choice)'. do you have to pick the one at character creation or can you just choose whichever suits you during play.
i'm sure the answer is somewhere in SR3, but i can't find it. thanks!
