[Dirty Shame]

So, I am looking and it seems that there is some seriously limited and confusing rules for this type of interaction. 

Below is the Astral Combat Table.  Does this mean that dual natured creatures uses these dice pools to attack astrally projected magicians/shamans? What if they have claws, does that count as unarmed?

Also, for weapon foci, they add to your Will Power for dice pool to hit, but what do they add to for damage? Strength? Willpower?

Dual Natured Being combat with Wholly Astral Being = Astral Combat
Dual Natured Being combat with Dual Natured Being = Physical Combat
Dual Natured Being combat with Wholly Physical Being = Physical Combat

Wholly Astral Being combat with Wholly Astral Being = Astral Combat
Wholly Astral Being combat with Dual Natured Being = Astral Combat
Wholly Astral Being combat with Wholly Physical Being = Not Possible

Wholly Physical Being combat with Wholly Astral Being = Not Possible
Wholly Physical Being combat with Dual Natured Being = Physical Combat
Wholly Physical Being combat with Wholly Physical Being = Physical Combat

Also, for weapon foci, they add to your Will Power for dice pool to hit, but what do they add to for damage?

Weapon focus add its force to your Close Combat (for Physical Combat) or Astral (for Astral Combat) skill and they deal the same (listed) base damage in Astral Combat as they do in Physical Combat.

Unarmed Combat deal Strength / 2 (round up) base damage while Unarmed Astral Combat deal Tradition Attribute / 2 (round up) base damage.

The base damage value is increased by +1 per net hit.
