Fighting Spirit

(Re-written 3rd level feature)

Starting at 3rd level, your intensity in battle can shield you and help you strike true. As a bonus action on your turn, you can give yourself advantage on all weapon attack rolls until the end of the current turn. When you do so, you also gain 5 temporary hit points. The number of hit points increases when you reach certain levels in this class, increasing to 10 at 10th level and 15 at 15th level.

You can use this feature three times. You regain all expended uses of it when you finish a short or long rest.
