Homebrew Ameonna Species Details

In Japanese folklore there is a Yokai known as the Ameonna. This creature is usually in the form of a woman so they were named with this in mind, though this does not mean they are exclusively female (for DnD). These creatures look human in most cases, and the only thing that sets them apart is that they seem to generate rain wherever they go. However, like all Yokai, they have their own abilities that set them apart from humans.
Other than being long lived creatures who do not physically age much after they reach maturity, the Ameonna have an affinity with water and thus have abilities to control water at will.
Other than when they are indoors, Ameonna always seem to have rain falling on them (even on sunny days) and though they usually use umbrella's their body and clothes are always drenched as their body is actually constantly creating water and releasing it onto their skin. As they get stronger they learn to control this and use the water released magically from their body to fuel their spells.

Your race is considered to be a Custom Lineage for any game feature that requires a certain race, such as elf or dwarf.
