Path of the Devil

"I really do not think this is a good idea. The Wizard said to his rouge friend who was currently stretching his arm with a shit eating grin on his face. "It's a great idea." he cheerfully stated. "All i gotta do is beat that large ofe in a simple arm wrestling match and that prize money is ours not to mention the large wager I placed on myself to win." "And how pray tell do you expect to win against that man who is several feet taller then you with your scrawny arms." the wizard stated exasperated with the rogues antics. "I got an ace in the hole" the rogue winked, nudging his companion and gesturing to a magical arm band he had strapped to his arm underneath his shirt. "With this little beauty I will have the strength of 10 men" he cackled with glee. The wizard sighed as he watched his rogue companion march up to the large cloak wearing man sitting at a table waiting for his next challenger. As the rogue sat down smiling ear to ear, setting up his arm in the ready position. "Get ready to fork that cash over big guy, and don't blame me if you end up with any broken bones." The cloaked man laughed "I like your spirit little guy. Since you are so confident, I think I will take this next round a little more seriously." And with that statement the man shifted his cloak aside and brought his offhand up revealing a huge muscular scaled arm that shook the table as he placed the monstrous arm on the table and quickly grasped the rouge's small hand into his massive hand completely dwarfing it. "Ready..." he stated, eyes glowing a brief crimson red. The rouge's face drained of color as he felt the bones in his hand already cracking underneath the man's grip even with his magic item active. "ohh...well this was a bad idea".

3rd Lv. Arm of the Devil

 Your Devil's Blood and/or power has allowed you to inherently understand the language of demonic creatures. The barbarian gains proficiency with the Abyssal Language. 

One of the barbarian's arms has manifested the aspect of a devil creature (you may choose what form your arm takes but it must be distinct and noticeable from the rest of your body). The devil's blood and/or power gives you supernatural strength allowing you to use a heavy weapon you have proficiency with in one hand. If you decide to use two weapons then the second weapon must have the light property. 

Your supernatural arm has the special property of manifesting a large magical arm  in the shape of that arm that can form around your devil arm or hover near it. As long as you are not using any other weapons or shields in your off hand devil arm then you may use your bonus action on each of your turns to apply one of the following effects. If any of these abilities target an object without an AC then they automatically fail their checks. Do not apply rage bonus damage to any of these features. 

Devil's Blow- Make an unarmed strike to a creature or object within sight of 15 feet of the barbarian dealing 1d6 magical bludgeoning damage on a hit. On a hit the target must make a strength check (athletics) or dexterity check (acrobatics) (the target may choose which one to use) against your own strength (athletics) check and on a fail are knocked 5ft. away and knocked prone. Targets 1 size category smaller or more than your barbarian make this check with disadvantage while targets that are more than 1 size categorys larger or more then your barbarian make this check with advantage with the exception of colossal sized creatures and larger who automatically succeed. 

Devil's Grasp- Target one creature or object within sight of 15 feet of the barbarian. That target must make a strength check (athletics) or dexterity check (acrobatics) (the target may choose which one to use) against your own strength (athletics) check and on a fail are put under the grappled condition and pulled to an unoccupied space within 5 feet of the barbarian. Targets 1 size category smaller or more than your barbarian make this check and subsequent grapple checks with disadvantage while targets that are 1 size category larger or more than your barbarian make this check and subsequent grapple checks with advantage with the exception of colossal sized creatures and larger who automatically succeed. A target grappled by this effect has disadvantage on their attack rolls. As a bonus action, if a target is grappled by this effect, the barbarian can throw the target 20 feet away and if the target hits an object or creature (make an attack roll against the creature or object using your strength based melee attack modifier) and on a hit both targets take 2d6 non-magical bludgeoning damage and must succeed on a dexterity saving throw and are knocked prone on a failed save (save dc is 8 + proficiency bonus + Strength modifier) (At the DM discretion, if the grappled target or hit target was magical then the attack becomes magical damage). A thrown grappled target loses the grappled condition.

6th Lv. Devil' s Endurance

Your Devil's blood and/or energy allows your rage to supercharge your natural healing abilities and defense when you are in the throes of combat. While the barbarian is in combat, moves 0 feet (forced movement not counted), and is raging then the barbarian can heal themselves 1d4 + constitution modifier at the end of each of their turns. 

While Raging, your barbarian has resistance to magical slashing, piercing, and bludgeoning damage.

10th Lv. Empowered Arm of the Devil

Your devil blood and/or power has evolved the power of your Devil's Arm. The range you can target a creature or object with your Devil's Grasp and Devil's Blow has increased to 30 feet. You now have advantage on all Devil's Blow and Devil's Grasp ability checks for any target that is one size class larger than the barbarian or lower. The barbarian can apply their rage damage modifier to the Devil's Blow and Devil's Grasp damage.

A target struck by your Devil's Blow is now knocked 15 feet away from the Barbarian when they fail their ability check against the Barbarian's Devil's Blow. Any inanimate object such as a wall or door, takes max damage when struck by your Devil's Blow.

Targets grappled by the Devil's Grasp and thrown can now be thrown and/or target other creatures and objects 30 feet away. When used on a restrained or immovable object such as a large statue, wall, or solid ground space as well as a huge sized creature or larger then the Barbarian can move towards that object or creature by up to a maximum of 30 feet with no coast to movement speed. This movement is considered a forced movement.

14th Lv. Devil's Fury

Your Devil's blood and/or power has enhanced your rage allowing the barbarian to bring the fury of hell itself right to your enemy's doorstep. While the barbarian is raging, Your Devil's Blow and Devil's Grasp features no longer have disadvantage on any sized target and can now affect any size target while you are raging. 

When your barbarian triggers its Relentless Rage feature, you may give yourself advantage on one of your saving throws. You can only use this feature once per short rest.
