Combat Momentum (5e Class Feature)
From D&D Wiki
Optional feature (replaces fighting style)
You gain access to a special resource in combat called Momentum. Whenever you hit a hostile creature with an attack during initiative order, you gain 1 stack of Momentum, up to an amount of stacks equal to your proficiency bonus. If the attack is a critical hit, you gain 2 stacks of Momentum. You lose 1 stack of Momentum if you end your turn having not made an attack against a hostile creature, or if you miss an attack made against a hostile creature. You lose all Momentum when initiative order ends or if you become incapacitated. Momentum can be used in the following ways:
- Each stack of Momentum you have increases the damage dealt by your attacks by 1.
- On your turn when you make an attack roll, you can choose to expend 1 stack of Momentum to make the attack roll with advantage.
- When you hit a creature with a melee attack, you can expend 2 stacks of Momentum to treat the attack as a shove attack, with the attack roll being used in place of the Strength (Athletics) check you would perform.
- On your turn, you may expend 1 stack of Momentum to make a single attack as a bonus action.
- As a reaction to a creature moving away from you, you can expend 2 stacks of Momentum to move up to your speed towards that creature.
- As a reaction to being hit with an attack, you can expend up to all stacks of Momentum, adding each stack to your armor class for the attack made against you, potentially turning the hit into a miss.
- Finally, when you take the attack action on your turn, you may choose to expend all stacks of Momentum, adding an extra die of damage for each Momentum spent to the first attack that hits on your turn.
