<< a shamen in my posse has used the above favour to put the turtles shell
favour on a feather, which he has given to another posse member.
my question is: is this a permanant power or a one use only? >>Well, this really depends on which blessing he placed on the feather, I will assume it was Imbue a Favor. To answer your question quickly, it is permanent, but it aint for free.Anyone who thinks this is incorrect, please, jump in and correct me.First, the posse member who now has the feather must first make a spirit roll to be granted the spirits aid. For members of its creator's tribe, this is a TN of (5) to activate, but if he/she is not a member of the creator's tribe, its a whopping (9).Second, the member has to have some Appeasement to actually power the favor, unless the item has Permanent Appeasement.
