Champion (Improved)

The Champion Fighter is a brutal master of attrition.

Aggression

Beginning when you choose this archetype at 3rd level, your weapon attacks score a critical hit on a roll of 19 or 20. Whenever you score a critical hit against a creature on your turn, you can make a single attack as a bonus action. Anytime you could make an attack you can instead make an object interaction action.

Endurance

At 7th level, you've learned exercise techniques and training routines to draw out your full physical potential. You gain the following benefits:

• You can add half your Constitution modifier(rounded up) to any Strength or Dexterity check or saving throw that doesn't use your proficiency bonus. For Constitution checks and saving throws, your Constitution modifier is doubled.
• Your movement speed is increased by an amount equal to 5 x your Constitution modifier.
• Your carrying capacity increases by an amount equal to your Constitution score multiplied by 15.
• You can push, drag, or lift an additional amount of weight, in pounds, up to 30 times your Constitution score.

Combat Savant

At 10th level, you learn two fighting styles of your choice.

Improved Aggression

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. In addition to this feature, your hit point maximum can't be reduced below half(rounded down) by effects.
