Third Wind
At 3rd level, when you use your Second Wind feature you also regain additional resources:
 * You regain one use of your War Banner feature.
 * You regain expended spell slots with a combined level that is equal to or less than one-quarter of your Fighter level, rounded up (see the Third Wind Table).

''For example, if you're a 4th-level Fighter, you can recover one level worth of spell slots. If you're a 7th-level Fighter, you can recover two levels worth of spell slots, which can be one 2nd-level spell slot, or two 1st-level spell slots. If you're a 15th level Fighter, you can recover up to four levels worth of spell slots, which can be one 3rd-level spell slot and one 1st-level spell slot, or two 2nd-level spell slots, or four 1st-level spell slots.''

War Banner
At 3rd level, you gain a war banner that you can use to empower your allies. You can also attach your war banner to a weapon with the reach property, as long as you are proficient with that weapon, turning it into a banner weapon. When you hit a creature with your banner weapon, you can immediately use your bonus action to choose one creature that you can see within 60 feet of you. The creature gains a Combat Inspiration die, which is a d4. The creature must be able to see or hear you to gain a Combat Inspiration die. Once within the next minute, the creature can roll the die and add the number rolled to one ability check, attack roll, or saving throw it makes. The creature can wait until after it rolls before deciding to use the Combat Inspiration die, but must decide before the DM says whether the roll succeeds or fails. Once the Combat Inspiration die is rolled, it is lost. A creature can have only one Combat Inspiration die at a time. Your Combat Inspiration die changes when you reach certain levels in this class: the die becomes a d6 at 5th level, a d8 at 10th level, and a d10 at 15th level.

You can use this feature a number of times equal to your Charisma modifier (a minimum of 2), and you regain any expended uses when you finish a long rest.

Shared Strength
At 7th level, as an Action, you can wave your banner with one hand until the start of your next turn, or you can plant it into the ground at an unoccupied location within 5 feet of you. While planted, your banner does not prevent movement through its space, it has an AC of 8, and 8 Hit Points. When you wave or plant your banner, you can choose one creature you can see within 60 feet of you that can see your banner or hear you. The creature gains one of the following abilities during it's next turn (your choice). You can plant or wave your flag twice, and you regain any expended uses when you finish a long rest.
 * Action Surge: The chosen creature take one additional action that turn.
 * Second Wind: The chosen creature can use a bonus action to regain hit points equal to 1d10 + your Fighter level.

Rally With Me
At 10th level, when you cast a Bard spell of 1st-level or higher and use your banner as the spellcasting focus for the spell, you can choose one of the following options.
 * You can make one weapon attack using your bonus action. If this attack hits, you can use your War Banner feature as part of the same bonus action.
 * You can plant or wave your banner as part of casting the spell (see your Shared Strength feature). If you do this, allied creatures within 30 feet of you can choose to use their Reaction to move up to their speed toward you. This movement can happen before or after you have finished casting the spell (your choice).
