Homebrew Elemental Genasi Species Details

Standing at over nine feet high, swirling with elemental power, lost in it's own desire to destroy, the genasi elemental is the genasi power fully released, fully unhinged and wanting for destruction. The genasi are steeped in power, given to them through their genie parentage, and over time most only ever learn to control this power, to use it to their will and want, but some, some can tap into the fathomless depth of that which was bestowed upon them.

This tapping isn't always voluntary, it is a violent and all consuming power, warping the form of the genasi into an elemental being,  a manifestation of pure energy of the genasi's temperament, air, earth, fire or water. When this transformation takes place the soul that had originally been the embodiment of the genasi is lost beneath an uncontrollable elemental force, violent in its view of the world, destruction its only desire.

The genasi soul can fight this power, strive to take some control back, to direct the violence accordingly, but in the same breath the power can swamp the genasi so greatly that it is just a tiny voice in the miasma of power. Unlike full elementals, the genasi elemental does not have the same longevity, once it has destroyed everything in it's local vicinity, or when it has been vanquished it will return to the core of the genasi and leave an exhausted and depleted individual

Elemental Genasi Traits

Uncontrollable Anger

Ability Score Increase

Your Constitution score increases by 2 and your Strength score increases by 3

Uncontrollable Anger

When a genasi relinquishes control to their elemental power they also succumb to the anger that this power brings. From level 3 the genasi can transform at any time into the genasi elemental. They will use their ability scores already created for the genasi but with the added ability scores defined in the traits for the genasi elemental.

If the genasi elemental loses any hit points it must take a test to see if the elemental power within takes control over the genasi soul. Once changed to the genasi elements, if any hit points are lost, in or out of combat the genasi elemental must roll a d20 and score under it's constitution score to remain as the genasi. If it fails then it sees everyone within a radius of 20 feet as an enemy, friend or foe alike. It will attack the closest and will continue to until they are either vanquished or the genasi manages to wrestle back control from the elemental power.  

The genasi can regain control by performing the above roll again at the start of its turn, if it succeeds then it cannot move but can still make any other action. If it fails then it will continue to attack the closest individual. 

Further to this, once the genasi elemental drops beneath half of its starting hit points then it must undertake this roll at disadvantage.

Ability Decrease

Once the genasi transforms into it's elemental form the Wisdom score is reduced by 2 and the Charisma score by 3
