Worth mentioning, for the Eldritch Scion at least:
Divine Anthology also has the Divine Fighting Technique "Desnas Shooting Star". It allows you to use your Charisma-modifier for attack and damage with a Starknife. Which isn't the best weapon for a Magus - it only has a 20 crit range - but going SAD can be pretty good.
I think it's worth a mention on the Charisma-magus at least.
