Blood Divination

You can drop a single drop of your blood into a bloodstain or sample of another creature's blood while casting this spell to created a magical resonance. This tells you the creature's current condition (if it is alive, wounded, or dead), its creature type, its general distance from you (nearby, distant, or far away), and its general direction.

If the blood is more than 24 hours old, the spell becomes more difficult, and you must pass DC 10 spellcasting check to gain any information, with the DC increasing to 15 if the blood is more than a week old, and 20 if the DC is more than a month old.
