Fighting Spirit

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
