The Frostveil Compass is a small, intricate device made of a crystalline material that glows faintly with an icy blue light. It is always cold to the touch, and its needle is made of a shard of enchanted ice that never melts. The compass is highly sensitive to supernatural cold, and its needle spins wildly in the presence of the ice phoenix or other magical ice formations. It is also resistant to extreme temperatures, making it a reliable tool in the harshest conditions.

The Frostveil Compass serves as a crucial navigation tool for detectives investigating the ice phoenix mystery. It guides them through the frozen landscape, revealing hidden paths and areas of supernatural activity. By following the compass's needle, detectives can uncover clues and avoid dangerous areas affected by the phoenix's magic.
