Glowstone Helmet

Glowstone helmets are usually of gnomish manufacture. While wearing this helm, you can use an action to cast a particular cantrip associated with that helmet (often dancing lights, light, mending, or sometimes produce flame). When combined with a frostglow weapon or a find the path spell, this helmet allows you to sense the direction and distance to the nearest ley line, shadow road, radiant well, and similar arcane landmarks.
