You can skill a healer for battle too - buy IN and AU later when they are still cheap, and CO and DEX at the beginning. Then you should give him a wand with Arrow of Light, so he can cast a damage spell without the need to change his active spell. And don´t forget:

and

have a Minimum-skill of 10 each and for spells IN is assumed as minimum 4.
I´d allow him to reskill his char (Level 2, right?):
BOD 5 MOB 7 MND 8
ST 0 AG 0 IN 1
CO 4 DX 5 AU 1+1 (rune robe)

19 /

11 (9+2 (complete Leather armor)) /

7 /

4.5 /

5 /

13 /

10 /

17 (13 +1 (quarterstaff) +1 (talents)) +2 (Arrow of Light)
Talents: Armor casting I + any other talent (perhaps Changing Spells I)
Culture Bonus: Shooting I (don´t know the English name of the talent that makes

and

+1 ... And the names of the others neither.

)
If he wants to use a bow (because a wand is expensive) he´d have

16 with an elven longbow. You could maximize it changing BOD to 4 and MOB to 8 to 17.
