Curse Of Achilles

The curse is named after Achilles,the Ancient Greek Hero,who was famous for his invulnerability. When one bathes in the Styx,they will be granted the power to remain uninjured by any means. They must get their parent's blessing. When one bathes in it, the person must envision one thing that ties them to the living. They also must imagine a single spot on their body with a rope tying them to the mortal plane. If they do not do this, they will turn into ash. Though not proven, the thing a person usually envisions is someone often close. An example of this is when Percy Jackson bathes in the styx,he envisioned Annabeth Chase,the girl he loves. The most obvious weakness is the mortal spot the person chooses,as it remains the only place that can be injured. Should this spot be injured,it's generally fatal.
