Subclass Abilities

Improved Critical

Beginning when you choose this archetype at 3rd level, your weapon attacks score a critical hit on a roll of 19 or 20. When you score a critical hit, you can make an additional attack with the same weapon, against the same or a different foe. If this happens on your turn and you have remaining movement, you can move between these attacks normally.

Remarkable Athlete

Starting at 7th level, you can add half your proficiency bonus (rounded up) to any Strength, Dexterity, or Constitution check you make that doesn't already use your proficiency bonus.

In addition, when you make a running long jump, the height and distance you can cover increases by a number of feet equal to your Strength modifier.

Finally, opponents with a level or challenge lower than yours cannot make attacks of opportunity against you.

Additional Fighting Style

At 10th level, you can choose a second option from the Fighting Style class feature.

Superior Critical

Starting at 15th level, your weapon attacks score a critical hit on a roll of 18-20.

Survivor

At 18th level, you attain the pinnacle of resilience in battle. At the start of each of your turns, you regain hit points equal to 5 + your Constitution modifier if you have no more than half of your hit points left. You don't gain this benefit if you have 0 hit points.
