Champion Variant

In this variant of the champion subclass improved and superior critical are replaced with an active ability called momentum.  Momentum is created during combat making the champion extremely deadly in short bursts they build toward.

Momentum

Momentum is a currency the PC gains during combat.  Momentum can only be gained, spent or lost inside of a combat scene.  Outside of combat momentum isn't generated.

Gaining momentum

Generating Momentum relies on consecutive attack actions during combat.  After two consecutive attack actions  (not attacks) in combat the PC gains a point of momentum.  Momentum is gained at the beginning of a PCs turn if they maintain their consecutive attack action chain.  A PC can only possess momentum equal to their Strength or Dexterity modifier.

If the PC gains advantage on any attack action roll they may instead roll normally and gain a point of momentum.

Spending momentum

Momentum can be spent to give yourself advantage on a single attack and or to add additional weapon dice to a damage roll after a successful attack.  There is no limit to the amount of momentum that can be spent at a time.

Losing momentum

Momentum is lost for each round you are unable to perform the attack action.  Suffering from the following conditions will remove all momentum:  blinded (unless the PC doesn't depend on sight for combat), Incapacitated, Paralyzed, Petrified, and Restrained.

Momentum - Critical Hit Threshold

The static benefit of accumulating momentum is for each momentum point you possess the PCs critical hit threshold is increased by 1.  If the PC has a Strength of 18 they can accumulate up to 4 momentum.  With 4 momentum the PCs critical role threshold is 16+.

The thought is once the PC scores a critical hit they will expend their momentum to buy damage dice to increase the critical hit damage.  On their next turn they will gain a momentum point by maintaining their attack action chain.  This allows their power to spike and then rebuild.

Remarkable Athlete

Starting at 7th level, you can add half your proficiency bonus (round 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 distance you can cover increases by a number of feet equal to your Strength modifier.

Great Weapon Fighting

When you roll a 1 or 2 on a damage die for an attack you make with a melee weapon that you are wielding with two hands, you can reroll the die and must use the new roll, even if the new roll is a 1 or a 2. The weapon must have the two-handed or versatile property for you to gain this benefit.

Protection

When a creature you can see attacks a target other than you that is within 5 feet of you, you can use your reaction to impose disadvantage on the attack roll. You must be wielding a shield.
