Champion, 2nd Variant (5e Subclass)
From D&D Wiki
The champion archetype in vanilla is good for beginners, but what if it were just a tad bit more? This is the overhauled champion, a fighter of true physical prowess and skill in combat. As a champion, you hone your body and its ability to perform past the human average and showcase battle prowess worthy of the term "Champion".
- Improved Critical
Beginning when you choose this subclass at 3rd level, your weapon attacks score a critical hit on a roll of 19 or 20. Roll an extra damage die on critical.
- Valiant Charge
Starting at 3rd level, when you make a melee weapon attack against a Large or smaller creature, you can force them to make a Constitution saving throw or be knocked prone. The DC for this saving throw is equal to 8 + your proficiency bonus + your Strength modifier. You can use this trait a number of times equal to your proficiency bonus +1 and regain all expended uses when you complete a long rest.
- War Cry
At 7th level, you can use a bonus action to shout out a cry of battle. All allies creatures within 30 feet of you gain advantage on their next attack roll they make in the next minute. Other creatures within range must succeed on a Wisdom saving throw or be frightened of you for the next minute. Once you use this feature you can't use it again until you finish a short or long rest.
- 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.
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.
