I want to make a full magician with an ally spirit that can manifest with the same aspect of my character. The problem is that the Ally Spirit is a huge Karma Sink and I don't think we will play for more than 10 sessions (at best), so the only option to have a character with an Ally Spirit is to start with one by using the spell points.
In order to make a decent Ally Spirit I will have to get 1m Yens and waste almost all in Spell Points. I'm still the only mage in the group (a shaman), so I want to spend at least 20 of the starting 25 spell points on spells. This leaves me with 5 points plus up to 25 points from the Newyens. (I can't buy more than 25 points due to have to totaling 50 at best).
So, how would you build a nice Ally Spirit with up to 30 karmas?
I'm sure I want to pay the Telepathic thing that costs 5 Karmas. This leaves me with 25 Karma and a starting Force of 1.
I could bring the force to 3 with 15 Karmas, bringing the total to 20 and maybe use the other 10 points to get him another skill (Etiquette?) and/or more spells.
I never made an Ally spirit myself and I really want to try one, help me building it

Thanks a lot
