Sentinal

"Stand your ground" is a common motto uttered by Sentinals in war, as they prepare to dig themselves in and prepare for their foes to launch their attack.

Battle Insight

When you choose this archetype at the 3rd level, you gain a special reaction when an attack is made against you you can make an insight check against your opponent's deception. if this check succeeds you add your Wisdom modifier to your AC for this attack.

Sentinel

Starting at 3rd level, your mastery as a defender becomes apparent.

• When you hit a creature with an opportunity attack, the creature's speed becomes 0 for the rest of the turn.
• Creatures provoke opportunity attacks from you even if they take the Disengage action before leaving your reach.
• When a creature within 5 feet of you makes an attack against a target other than you (and that target doesn't have this feat), you can use your reaction to make a melee weapon attack against the attacking creature.

Unwavering Mark

Starting at 3rd level, you can menace your foes, foiling their attacks and punishing them for harming others. When you hit a creature with a melee weapon attack, you can mark the creature until the end of your next turn. This effect ends early if you are incapacitated or you die, or if someone else marks the creature.

While it is within 5 feet of you, a creature marked by you has disadvantage on any attack roll that doesn’t target you.

In addition, if a creature marked by you deals damage to anyone other than you, you can make a special melee weapon attack against the marked creature as a bonus action on your next turn. You have advantage on the attack roll, and if it hits, the attack’s weapon deals extra damage to the target equal to half your fighter level.

Regardless of the number of creatures you mark, you can make this special attack a number of times equal to your Strength modifier (minimum of once), and you regain all expended uses of it when you finish a long rest.

Warding Maneuver

At 7th level, you learn to fend off strikes directed at you, or other creatures nearby. If you or a creature you can see within 5 feet of you is hit by an attack, you can roll 1d8 as a reaction if you’re wielding a melee weapon or a shield. Roll the die, and add the number rolled to the target’s AC against that attack. If the attack still hits, the target has resistance against the attack’s damage.

You can use this feature a number of times equal to your Constitution modifier (minimum of once), and you regain all expended uses of it when you finish a long rest.

Hold the Line

At 10th level, you become a master of locking down your enemies. Creatures provoke an opportunity attack from you when they move 5 feet or more while within your reach, and if you hit a creature with an opportunity attack, you regain your reaction

Unmoving Defence

Starting at 15th level, you gain defense each turn you do not move, this extra defense stacks by 1 every turn you do not move. in addition you can cast Meld into stone once per long rest

Vigilant Defender

Starting at 18th level, you respond to danger with extraordinary vigilance. In combat, you get a special reaction that you can take once on every creature’s turn, except your turn. You can use this special reaction only to make an opportunity attack, and you can’t use it on the same turn that you take your normal reaction.
