Ronin

The Ronin is a fighter who has no master but still draws on an implacable fighting spirit to overcome enemies.

When choosing Ronin as your subclass you can choose 1 artifact items, 2 rare items, and 4 uncommon items.

Level 3: Fighting Spirit

As a bonus action, you can give yourself advantage on weapon attack rolls until the end of the current turn and give yourself 10 temporary HP.

Level 3: Remarkable Athlete

Thanks to your athleticism, you have Advantage on Initiative rolls and Strength (Athletics) checks.

In addition, immediately after you score a Critical Hit, you can move up to half your Speed without provoking Opportunity Attacks.

Level 7: Additional Feat

You gain another Feat of your choice.

Level 10: Strength before Death

Starting at 10th 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.

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

Level 15: Superior Critical

Your attack rolls with weapons and Unarmed Strikes can now score a Critical Hit on a roll of 18–20 on the d20.

Level 18: Retaliation

When you take damage from a creature that is within 5 feet of you, you can take a Reaction to make one melee attack against that creature, using a weapon or an Unarmed Strike.
