Chapter 10 · Wondrous Item

Lower Realm Lantern

Effect
A lantern of void-glass and infernal iron that produces light functioning normally in all lower-realm environments. Light radius 40 feet clear, 40 feet dim beyond. Magical darkness does not affect it. Acts as a planar compass calibrated for lower-realm navigation: pulses when high-entropy areas are within 500 feet, faster as proximity increases.
Uses
Permanent lamp. Requires refilling every 8 hours with standard oil.

About

The infernal iron is what allows it to penetrate magical darkness - the lower realms recognize their own material and do not obstruct it.
