Base Class: Fighter
"I should be dead." The mage stated, staring up at the massive figure that had stepped between him and the dragon's flame. The towering form, it's gender indeterminant from within it's casing of full plate and plumed helmet, turned to stare down at the mage. "And yet, you are not. With me!"
Protection Warriors are bastions of both endurance and physical strength: They excel in battles with high amounts of physical attacks, or where mobility is needed. With their natural proficiency in the heaviest of armors, they can shrug off blows that would have left many of their allies unquestionably dead.
Defensive Stance
Beginning when you choose this archetype at 3rd level, the AC benefit you receive from shields improves by 2.
Challenging Shout
Starting at 7th level, you can unleash a mighty roar, making yourself the largest, most bombastic threat on the battlefield. All foes that can hear you must make a Wisdom saving throw with a DC = to 10 + your Fighter Level. If they fail, they have disadvantage on all attacks made on any target other than you for 1 minute.
This has no effect on creatures that cannot hear but ignores immunities to compulsion effects.
Revenge
Starting at 10th level, any time an enemy successfully damages you or an ally within 5 feet of you, you can use your Reaction to take an opportunity attack against that target.
Critical Block
Starting at 15th level, you can deny a critical attack against you or an ally and change it to a normal strike. You may declare this action before or after the damage has been rolled. You may only perform this feature once per short rest.
Last Stand
At 18th level, you attain the pinnacle of resilience in battle. You may use your Hit Die you'd normally use during a short rest to grant yourself Temp HP equal to the Hit Die rolled. You take an amount of damage equal to the amount of Temp HP rolled after combat ends, or 1 minute (10 rounds) later, whichever comes first. You can use as many or as few Hit Die as you wish, but these Hit Die do not regenerate until you finish a long rest, and you cannot usee this ability more than once per long rest.
