Vassal Defender

Update to the current Samurai

Bushido

When you choose this archetype at 3rd level, you gain the ability to undo a failed saving throw or ability check if it is done in the presence of others. Once per short or long rest, if you fail an ability check or saving throw within 30ft of an ally you can choose to re-roll the ability check or saving throw. You must use the re-rolled number. Gain an additional use at level 10 and level 18.

Vassal

Starting at 3rd level, you may swear your loyalty toward an ally. As a bonus action, you can target an ally within 30 ft of you and become their vassal. Both you and your targeted ally gain +1 to your armor class while within 30 ft of each other. When an attack you can see targets your ally, you may spend your reaction to have it target you if you are within 30 ft of your targeted ally. 

You remain the vassal of your target until you chose to use this feature again, even in death your service remains.

You can use this feature proficiency modifier times and you regain all expended uses of it when you finish a short or long rest.

Strategic Artisan

Starting at 7th level, your discipline and attention to detail allow you to excel in the art of war and as a vassal. You are a student of war as much as you are warrior. You are now proficient in perception (Perception), if you already are you may chose any wisdom based skill. You gain a {{modifier:wis}} bonus to any check made to study an enemy or a piece of artistry, and you gain proficiency in WIS saving throws (or INT or CHA if you already are).

Mystic Fortitude

Starting at 10th level, while within 30 ft of your vassal target, you and your target gain advantage on saving throws against magic.

Critical Strike

Starting at 15th level, you learn to study a foe and bring them down in one swift strike. Once per turn, if you take the Attack action on your turn and are within 30 feet of your vassal target, you may forgo one of your attacks in order for the next attack to score a critical hit. You may use this feature proficiency bonus number of times before needing to take a long rest.

Service beyond Death

Starting at 18th level, your fighting spirit can delay the grasp of death. If you take damage that reduces you to 0 hit points and doesn’t kill you outright, you can use your reaction to delay falling unconscious, and you can immediately take an extra turn, interrupting the current turn. While you have 0 hit points during that extra turn, taking damage causes death saving throw failures as normal, and three death saving throw failures can still kill you. When the extra turn ends, you fall unconscious if you still have 0 hit points. If you are within 30 ft of your vassal all benefits of the vassal ability remain in tack.

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