Path of the Blood rager

The path of the bloodrager becomes stronger the more hurt they become.

Power from pain

While raging, you deal additional damage based on your current remaining hitpoints. At 3rd level you deal 1d6 additional damage on each of your attacks when you are below 2/3 of your total max hp, and an additional 1d8 while below 1/3 of your max hp. when you reach 7h level in this class these increase to 1d10 and 1d12 respectivelyion].

Get mad

Beginning at 6th level, When you roll a 10 or lower on a tool or skill check, you may choose to roll another d20. You must use the new roll. Potentially ending up with a lower roll.

Failing a roll when using 'Get mad' may worsen the effect of the failed roll. 

Final stand

Starting at 10th level. Once during each of your rages, when you are below 1/3 max hp (rounded up) or when you are brought to 0hp you may declare a final stand. If you do, you immediately gain temporary hp equal to 1/3 of your max hp (rounded up) and you may double the dice granted by your Power from pain feature.  This effect will last until the end of your rage. Additionally, while this effect is active, you must make each of your attacks reckless and if you are brought down to 0hp while this effect is active you immediately die. .

Protective strike

Starting at 14th level, When an creature standing within 20 ft of you deals damage to one of your allies you may use a reaction to close the distance and make a melee weapon attack against that creature. you take damage from a creature that is within 5 feet of you, you can use your reaction to make a melee weapon attack against that creature.
