Favored ability scores

[Valdur]

Aside from being able to use a hope point on a favored skill or specifically where it is written in certain abilities what benefit are favored ability scores? When attacking with a favored weapon and using a hope point do you add the favored bonus? Or when you roll a Tengwar rune do you add the favored? Can you add your favored WITS to your parry?

[Yusei]

When you spend Hope on a favoured skill, you add your favoured attribute.
Nothing special happens when you run a tengwar rune on a favoured skill roll (but it's still a great or extraordinary success)
You don't add your favoured Wits to your parry score, unless you have a virtue or cultural blessing that says so.
