An exploration lens is a magical glass lens designed for a Bull's Eye Lantern. When light from the lantern passes through the lens, it alters the light to make it easier to perform a common exploration activity with the lantern.
Alternatively, an exploration lens can be installed in a Wayfinder like an aeon stone. In this case, light (such as that from a Lantern (Hooded), Torch, or Light spell) must still pass through the lens and you must hold the wayfinder in your hand for it to function.
There are several different types of exploration lens, each granting benefits with a different type of exploration activity. Each type of lens is distinguishable from all the other types by holding it up to a bright light.
Type: Investigating
The outer rim of this lens glows faintly when held up to the light.
While activated, the lens grants you a +1 item bonus to skill checks to Recall Knowledge while Investigating by outlining potential clues in a way that triggers your memory.
If you're Investigating something while using the lens, you can always roll a Recall Knowledge skill check appropriate to the investigation for initiative.
Traits
Something of uncommon rarity requires special training or comes from a particular culture or part of the world. Some character choices give access to uncommon options, and the GM can choose to allow access for anyone. Less is known about uncommon creatures than common creatures. They typically can't be summoned. The DC of Recall Knowledge checks related to these creature is increased by 2.
DivinationThe divination school of magic typically involves obtaining or transferring information, or predicting events.
InvestedA character can wear only 10 magical items that have the invested trait. None of the magical effects of the item apply if the character hasn't invested it, nor can it be activated, though the character still gains any normal benefits from wearing the physical item (like a hat keeping rain off their head).
MagicalSomething with the magical trait is imbued with magical energies not tied to a specific tradition of magic. A magical item radiates a magic aura infused with its dominant school of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
