Scrappers are fighters who rarely win a fight....but they sure as hell never lose. 

Force of Will

When you choose this archetype at 3rd level, you learn techniques that keep you in the fight that are fueled by special dice called Willpower dice.

• Once per turn when you can add Willpower die to a missed attack roll, possibly turning that attack into a success.
• As a reaction you can add a  Willpower die to saving throw
• When you are forced to roll a death save you can add a Willpower die to the roll. If this roll makes the result greater than or equal to 20 then you treat the result as that having rolled a natural 20
• When you use your Second Wind ability you can add a Willpower die to the total
• When you roll a  Strength, Dexterity, or Constituion ability check you can choose to add a Willpower die to the result.

Willpower Dice. You have four willpower dice, which are d4s. A willpower die is expended when you use it. You regain all of your expended willpower dice when you finish a short or long rest.

You gain another willpower die at 7th level and one more at 15th level.

Ain't No Time for Fear

Improved Force of Will

At 10th level, your willpower dice turn into d8s. At 18th level, they turn into d10s.

Down but not Out

At 15th level, you refuse to give up even in the most dire situations. When you drop to 0 HP you can use a reaction to roll a Willpower die and immediately gain HP equal to the roll + your fighter level. Until the end of your next turn you gain resistance to all damage.

When you use this feature you cannot use it again until you complete a long rest.
