Once a Demigod reaches their early teens (or the non-human equivalent), they release a scent that some monsters can detect. The strength of this scent varies depending on the strength of the godly parent; a minor deity's scent is more muted, but the scent of the Big Three gods - Zeus, Poseidon, and Hades - is much stronger. This scent can be masked in various ways, but once a demigod learns that they are descended from a god, it is much harder to control. The Mist shrouds these monsters from most mortals, but they will stalk their prey until they are destroyed. That is why there are
various safe havens created for demigods to be brought to, where they can live in peace among one another. Many demigods do not know their lineage until they are attacked, which makes for a very jarring transition. Some demigods do choose to leave their haven and live in the mortal world for part or all of the year, but it can be very dangerous to do so.

Demigods are hardwired for the speech and warfare of ancient cultures, which may make them behave differently from their peers. Several have ADHD and dyslexia, finding relief in exotic languages like Greek or Latin, and the stimulating environment of combat. The safe havens where demigods are brought often feature training courses, combat mentors, and the tools necessary to hone their preternatural skills. Oftentimes, a god will not "claim" their demigod child until they demonstrate some form of their parent's traits, like Apollo's skill at archery or Poseidon's control over the water.

Most demigods want to be claimed and recognized by their godly parent, seeking out their parent's approval - a common trait among many races. Some lucky demigods will even be given a quest, which usually involves receiving a prophecy and accomplishing an act of importance to the gods. Quests are also great ways for a demigod to demonstrate their worth, and for the DM to utilize as a hook for a campaign.
