Like the title says.

For Gallica I think the usual navigator stuff is a given, revealing a new enemy's resistances and the like. Though given that she has equipment I can see her getting a follow up attack with the Protag.

For More I can see increased MAG and A-EXP gains.

Maria could give you ingredients or even meals.

Brigitta would be like the other shop keepers, giving you a wider selection and discounts.

For Neuras improvements to the Gauntlet Runner like more facilities or faster travel times.

Improved Social stat gains could be broken up, like one follower for Wisdom and another for Eloquence.

Would love to see what you guys think.
