Fighting Spirit

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 long rest.
