I'm building an Ally spirit for my little shaman, but I've a snag trying to figure it out.
What are the ally's Mental Attributes set to?
Physical and Astral are equal to force.
Edge is equal to Summoner's at time of summoning.
Force is set by Ally Formula, and is used in place of Magic by spirits
But what about Mental?
They're not mentioned specifically, although the last paragraph under Losing an Ally (street magic pg 106) does mention that the ally spirits are "every bit as intellegent as its conjuror". And in 3rd edition, When you summoned an ally, it did explicitly take on the Mental attributes of the conjuror, rather then using it's Force for it's mental capacity.
I think that's what we're still supposed to be doing. Afterall, through the rest of the books, the rules are pretty specific about Physical / Mental / Astral attributes being distinct from each other. So when pg 105 says Ally's attributes (both physical and mental) are equal to force, I don't believe that's meant to cover mental.
And, naturally, the FAQ and Errata are silent on the matter.
