It is often said offense makes the best defense. The famed Shield Masters of Ordo Tarakona say nay to that. Armed with multiple shields these dragon warriors form an impenetrable barrier protecting their allies and frustrating their enemies.

Tarakona Training

Starting at 3rd level when you choose this Fighter Subclass you learn how to fight effectively with shields. You gain proficiency with shields as weapons with the following traits. A normal shield deals 1d6 bludgeoning damage and has the light, finesse and versatile(1d8) properties. In addition, you may also equip an additional shield. This shield grants a bonus to your AC equal to half its bonus rounded down.

Defensive Reflex

Starting at 3rd level, you can spend your reaction to add your proficiency bonus to your AC against melee or range weapon attacks, or any ally within 5 ft. of you. You can use this feature a number of times equal to your strength modifier.

Shield Parry

At 7th level you learn how to parry your opponent's attacks. When you are targeted with a melee attack, you may use your reaction to attempt to parry it. You roll as if you were attacking with your shield, if your roll beats theirs, you parry the attack, causing it to miss. You can use this feature once until you finish a short or long rest. At level 13 you gain an additional use of this ability.

Dragon Wall

At 10th level, you spend your action to create a shield wall. You and every creature in a 5 ft. cone behind you gain the benefit of three-quarters-cover. (On a grid map this would cover your space and the 3 squares behind you forming a short T of safety.) Once you use this feature your speed is reduced to 0 until the end of your next turn. You must have two shields equipped to use this feature. You can use this feature once per long rest.

Shield Mastery

At 15 level you may add the full bonus of both shields to your AC.

Thick as Dragon's Hide

At 18th level if you are hit by an attack you may choose to block the attack and take no damage. If you block an attack with an area of effect with a point of origin such as a dragon's breath or a fireball none of the targets take damage except you. You cannot use this ability again until the end of a long rest.
