I know squires normally don't fight for the knight, but out of curiosity, what is the standard sword skill of a player knight's squire?

10. Horsemanship, First Aid and Sword start at 10. They also get one other skill of your choice. You can increase 3 of these by one point per year until age 20 whereupon you have to roll 1 on a d6 to increase them - assuming your squire stays with you.
