You are an Elemental.

Due to the time and effort a storm elemental must put in to become an Electrofolk, most Electrofolk have a deep desire to properly integrate into mortal society. Even the rowdiest storm elementals tend to calm in the millennia it takes for them to fully adopt an Electrofolk form. Most Electrofolk tend towards lawful and good alignments, and while it is exceedingly rare to find chaotic or evil Electrofolk, it is certainly not impossible.

Your size is Medium (about 5–6 feet tall).

As Electrofolk come from storm elementals, it usually takes about 3,000 years for a storm elemental to become an Electrofolk, if it chooses to do so. Due to the time it takes to actually become an Electrofolk, all Electrofolk that exist are considered physically mature, but usually take between 15 and 20 years to become emotionally mature by mortal standards. Once again tying into their elemental nature, they can live indefinitely if left undisturbed.

Your base walking speed is 40 feet.

You can move through a space as narrow as 1 inch wide without squeezing, provided you are wearing and carrying nothing. Any creature that touches the Electrofolk must succeed on a DC 12 Constitution saving throw or take 1d4 lightning damage.

You gain a fly speed (hover) equal to half your speed. Additionally, you cannot fly further than 5 feet above the ground with a fly speed granted from this ability.

You can use this feature a number of times equal to your proficiency bonus. You regain all expended uses when you finish a long rest.

You take 1 cold damage for every 5 feet you move in water, or for every gallon of water splashed on you. If you start your turn while completely submerged in water, you takes 3d10 cold damage. The body of an Electrofolk that dies to cold damage in this way disperses into the air.

You have resistance to lightning damage.

Your character knows at least three languages: Common, Primordial, and one language you roll or choose from the Standard Languages table. Knowledge of a language means your character can communicate in it, read it, and write it. Your class and other features might also give you languages.

The Standard Languages table lists languages that are widespread on D&D worlds. Every player character knows Common, which originated in the planar metropolis of Sigil, the hub of the multiverse. The other standard languages originated with the first members of the most prominent species in the worlds of D&D and have since spread widely.
