Path of the Abomination

Whether through experimentation, intervention or ancestry, the primal rage within you has become so profound it has manifest into a dark and menacing entity. Lurking in the dark reaches of your mind, the Abomination surfaces during moments of great stress, taking control of your mind and twisting your body into a monstrous form. The Abomination is a thing to be feared, to be supressed, controlled or destroyed, for if it escapes and takes control, it would wreck havoc upon the world.

The Abomination

Starting when you choose this path at 3rd level, whenever you enter a rage your body twists and morphs into something monstrous, the malevolent force of the Abomination takes control and while raging, if your Intelligence score is higher than your Strength score, swap the scores until your rage ends.

Unstable Rage

At level 3, the Abomination's fury grows as it is threatened. Immediately when hit by an attack that deals damage to you, roll a d20, if you roll a 1 on that die immediately roll a d100 and use the effect from the Unstable Rage table, this effect lasts until the end of your rage (Unless stated otherwise) and you cannot willingly drop your rage until the end of your next turn. Each time you take damage and don't roll a 1, increase the score of the die roll by an additional 1, this effect resets when an effect is applied from the Unstable Rage table.

Brokered Assistance

Beginning at 6th level, you gain proficiency in Intelligence saving throws. In addition you and your Abomination have learnt to work together in shared goals. While not in a rage you may give yourself advantage on any Strength check or saving throw. While in a rage, you may give yourself advantage on any Intelligence check or saving throw. You may use this feature a number of times equal to your proficiency modifier, and you regain all expended uses on a short rest. 

Unstoppable Rage

When you reach level 10, Your connection to the Abomination is getting stronger, you feel you could in time learn to live with one another. As a bonus action when you would be under the effect of the Unstable Rage effect, you can forgo the roll and immediately choose an effect from the table. You may use this feature a number of times equal to your constitution modifier, and you regain all expended uses of it when you finish a long rest.

Repressed Intellect

Starting at 14th level, your Intelligence score maximum is increased to 24. 

Surrender Control

Also at 14th Level, before you would make a death saving throw, you may instead choose to trigger option 99-100 of the Unstable Rage table. If you do you regain 1 HP, roll half of your remaining Hit Dice and gain Temporary HP equal to the total and stand up if you are prone. You cannot use this feature if already under the effects of option 99-100 on the Unstable Rage table.
