Martial Archetype

Hoplite

Hoplites are fearless warriors, trained to fight in the phalanx formation. Interlocking their shields, they form an impenetrable wall, all the while attacking with reach weapons.

Phalanx Formation

Beginning when you choose this archetype at 3rd level, you gain a +1 bonus to AC for each ally within 5 feet of you that is wielding a shield. Allies within 5 feet of you also gain a +1 bonus to AC while you are wielding a shield.

You and allies you affect in this way may get this bonus a maximum of one time. This increases to two times at 7th, and three times at 15th level.

Strike and Thrust

Also at 3rd level, simple melee weapons with the versatile property gain the reach property for you, and always deal their versatile damage as long as you are wielding a shield in the other hand.

Peak Physique

At 7th level, your martial training has perfected your physical condition. You gain advantage on any Strength and Constitution checks you make.

With It or On It

Starting at 10th level, you can't be frightened by any means.

Additionally, whenever an ally within 10 feet of you that you can see becomes frightened, you can use your reaction to end the condition on them.

Once you use this feature, you can't use it again until you finish a short or long rest.

Shield Counter

At 15th level, you can use shield and weapon to retaliate against failed attacks. When a creature misses you with a melee attack, you can use your reaction attempting to knock them prone with your shield. Make a Strength (Athletics) check contested by the target's Strength (Athletics) or Dexterity (Acrobatics) check (target's choice).

If you win the contest, the target is knocked prone and you can follow up with a melee weapon attack against the target.

Last Stand

Starting at 18th level, when you are reduced to 0 hit points and not killed outright, you can immediately take a full turn before falling unconscious. If you regain any hit points during this turn, you aren't knocked unconscious.

Once you use this feature, you can't use it again until you finish a long rest.
