Mortal Guardian Knacks gift you with the vast fortitude and sharp senses, to better protect those you have sworn to guard. Guardian Knacks are driven by the concepts of durability and protection.
Guardian Knacks revolve around choosing a specific person to protect. When choosing who is worth of your divine protection, bear in mind that — unless they’ve completely neglected to invest in any sort of combat abilities — your bandmates do not need you to be the wall between them and your enemies. They should, for the most part, be able to handle that themselves. This is not to say that the Storyguide should forbid you from using these abilities on your bandmates, especially when it would be cool or dramatic, but that the intent is that a Guardian Scion protects those who are weaker than herself.
