Legionnaire

Legionnaire Drawn from across the Empire and trained ceaselessly in the arts of war, the Roman Legionnaire is the preeminent professional soldier of the ancient Mediterranean world. Carrying their trusty scutum, several pila javelins, a gladius or spatha, and enough siege equipment to fortify an indefensible position in under a day, the Legionnaire is prepared for any engagement in any terrain.

Pila Volley At 3rd level, you have mastered the Roman legionary javelin, the pila. You gain proficiency in thrown weapons, and may add double your proficiency when you roll to hit with a pila. In addition, when you roll a critical hit with a thrown pila against an enemy that is using a shield, the pila's head crumples and embeds itself in the shield, rendering both the pila and the shield useless (the enemy loses any AC they gained from the now crippled shield until they take a minute to extricate the crumpled pila, and the pila itself is permanently damaged beyond repair).

Shield Bash At 7th level, you know how to turn the humble legionary scutum into an offensive weapon. As a bonus action, you can make a Shield Bash (Melee Weapon Attack + Proficiency Bonus to hit, Reach 5 ft, One Target. Hit: 1d6 + Strength bludgeoning damage) against a target in range. On a hit, the target must succeed on a Strength save (equal to 8 + your Strength Modifier + Proficiency Bonus) or be knocked prone. You can use this ability a number of times equal to your Strength modifier. At 10th level, you have advantage on the roll to hit with this ability, and at 13th level, the bludgeoning damage increases to 1d12 + Strength.

We Stand As One At 10th level, you know how to stand with your allies as a solid line of steel and blades. When you are within 5 feet of an ally, both you and the ally gain +1 to armor class. The ally must be to one side of you for the feature to apply, not in front of you, behind you, or diagonal. If you are within 5 feet of two allies, you gain +2 AC (though the benefit to each ally remains +1).

Aquiline Discipline At 14th level, you have been trained to ignore fear and doubt on the battlefield. You have advantage on saving throws against being Frightened or Charmed.

Centurion’s Rally At 18th level, you are a commanding presence, and your voice demands obedience. You may issue orders to any three allies you can see within range. These allies each receive one of the following: Advantage on their attacks for a turn, an immediate Disengage action free of an attack of opportunity, or a +3 to their AC for one round. This feature may be used a number of times equal to your Charisma modifier.
