Kaizoga

Overview
A Kaizoga is a Rare Type of Elemental who is born with the ability to use any element they can think of at any age, but using any element makes the Elemental age at a span of 5 months per 3 seconds. They are technically immortal to age however, because if they use their element to pass or to the age of 90, they will be shrouded in light and become a child again. If they don't use their element past 90 at all then they could and will at some point die of old age, they get a choice if they want to live, if not then they will just wait it out. Once it is done enough times a person can instantly skip childhood if they continue using their abilities after rebirth. They can and will die from stab wounds or anything else that is not aging.

Side Effects/Downfalls
People who are a Kaizoga take more damage from things and can die from one stab wound to the heart, unlike most Elementals, who have a chance of survival.
