Braggart

Not just any fighter eager to show off and impress is an archetypal braggart. Braggarts elevate showing off and telling tall tales to an art imbued with magic, allowing them to perform uniquely during combat.

Boastful Shout

Beginning when you choose this archetype at 3rd level, during your first turn of combat , when you reduce a creature to 0 health, or when you score a critical hit, you may use your bonus action to boast. Enemy creatures within 30ft of you that can hear you make a wisdom saving throw against 8 + your proficiency bonus + your charisma modifier. You and your allies have advantage on attack rolls to attack creatures that fail this saving throw until the end of your next turn. Creatures that are immune to being charmed are immune to this part of the effect.

Tall Tales

Impeccable, untouchtable

Starting at 10th level, Whenever you make an attack with advantage, you may add half your charisma modifier rounded up to your attack roll and damage roll for that attack. Whenever a creature attacks you with disadvantage, you may add half your charisma modifier rounded up to your AC for that attack.

Terrifying notoriety

Simply the best
