I'm not sure if this is correct, but I've done some work on the Empty Vessel. We're given the skill modifiers without the spirit, so I used these to calculate the number of ranks the 4th level telepath put into Sense motive, Bluff, and Knowledge: the Planes. 4 each.

That gives us ability modifiers to those skills of +3 int mod, +4 Wis mod, and +3 Cha mod. That's what the telepath has. However, the " Characters normally have these scores before adjustments " gives us 13, 14 15, for... +4 Int, +4 Wis and +2 Cha. If we take into account +1 int for 4th level, and therefore a +2 Int mod.

If we do the traditional all 10 scores, the scores fit for -2 Dex, +2 Dex, +6 int, +8 Wis, +6 Cha. That's a bit extreme. Which one is correct? If at all?
