Draft said:I believe that the highest FA skill in the party determines how much is healed. So while your character may have no FA skill, if Liara is in the party and has it maxed, when your character uses the med pack, it heals the most possible.
I think the FA skill stacks, so that the skill level of all party members is added together. It's the only skill that does that in the game I believe. At least according to the Gamespot guide.
