Paper,
Using a weapon focus will allow you to take the astral combat spec in your weapon, giving you your dice to all opponents as long as you have it active.
If you can use Sum to 10, going dwarf (raising Meta to C) and droping attributes to C would allow you to have a 7 Will (losing 2 points somewhere to go up from 5, Reaction?) Your aptitude for astral combat could then put the skill at 7. This gives you 14 dice plus specialization. The weapon focus would give you another bonus based on the force of the focus. You would have to drop your Charisma to 5 (only one maxed attribute), and lose two more point of attribute (agility?). Edge would go down by one. Outside going adept, not sure how else to get those dice up.
