Mighty Unarmed Strikes. Borba's unarmed strikes deal 1d4+4 bludgeoning damage and, against a Large or smaller creature, force that creature to make a DC 15 STR saving throw. On a failed save, the creature is either pushed 15ft back or knocked prone (your choice).
Spellcasting. Borba is a 0-level spellcaster. Her spellcasting ability is STR (spell save DC 0, +0 to hit with spell attacks). Borba has the following Barbarian spells prepared:
Cantrip (at will): Fist*
*"Fist" is a totally real Cantrip requiring Verbal, Somatic, and Material components. Verbal: state an aggressive statement to your foe. Somatic: clench your fist. Material: a knuckle sandwich. Then, make an unarmed strike against any foe within 5ft.
Rallying War Cry. Once per Short Rest, Borba can expend an action to let out a rallying war cry to inspire up to three allies within 30ft of her. Each ally inspired in this way receives 1 Inspiration Charge for the next 1 minute. When an inspired ally misses an attack roll, that ally may expend its Inspiration Charge to reroll the attack roll. If the attack roll had disadvantage, it no longer rolls with disadvantage for the reroll.
Enormous Greatclub. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) bludgeoning damage.
Javelin. Ranged Weapon Attack: +7 to hit, range 30/120 ft., 1 target. Hit: 8 (1d6 + 4) Piercing damage.
Rage. Once per Long Rest, Borba can expend a bonus action to activate the Barbarian Rage feature on herself.
