Defender

With their otherworldly reaction speed and indomitable will, they will stop at nothing to keep those around them safe. You must be wielding a shield in order to use any features from this archetype. Any feature that requires a target to make a saving throw has a DC equal to 8 + your proficiency bonus + your Constitution modifier.

Always Ready

Starting at 3rd level, you are always on the watch for danger. You gain a +1 to your AC, and proficiency in the Perception skill. If you already are proficient,, you can double your proficiency bonus for the skill.

Guardian's Leap

When you choose this archetype at 3rd level, you resolve to protect your allies by becoming their shield. When an ally you can see within 5 feet of you is the target of a creature's attack roll, you can use your reaction to leap in between your ally and the enemy as long as you are not prone, grappled, or restrained. You move up to 5 feet into your ally's space, and your ally must have an unoccupied space within 5 feet of them that they take during the move. Your ally's movement does not provoke opportunity attacks. This makes you the new target of the triggering attack roll, and you can reduce the damage by 1D6 + your fighter level against that attack (This feature increases by 1D6 at level 9 and 18).

Protective Stance

At 3rd level, you learn how to widen your stance in order to allow allies to use you as cover. Creatures of your size or smaller you choose can use you as a source of half-cover, so long as you are not blinded, incapacitated, prone, grappled, or restrained. The creatures must be within 5 feet of you and you must be in between them and the source of the attack. In addition, when you use your Second Wind feature, any creatures covered by you regain the same amount of hit points you do
