Well, I was thinking about more mundane and ambient things:
Mushrooms
These mushrooms, while clearly not luminescing, smell of damp and mould. However, they taste exceptional and provide a variety of nutrients.
Special Item / 1 time use. (eat mushrooms)
Does nothing but fill your belly! :D
Alchemist's Mineral Acid
Created from different combinations of mineral salts and chemicals, the resulting acid is a sticky substance that can dissolve rocks, minerals, and other types of earth.
Throwing Weapon / 1 use (throws acid flask to dissolve rock/ damage earth-related creatures 1d6 damage)
Orog Whip
These whips are of a cruel design - three long strands ending in leather studs. They are used by the Orog's to discipline poorly behaved slaves (though they are known to be used on any slave). The lashes are known to leave horrible scars.
No real use, or maybe a 1d6 damage.
Drueger Gloves
These gloves are heavy, thick and have a musky odor. From the hairs on the gloves, you discern that they seem to have been fashioned from a make-shift leather, possibly from a Minotaur or some other creature. They are exremely durable and protect the wearers hands from and sharp edges.
No special bonuses.
Orog boots
You are reluctant to wear these boots, since they are extremely heavy, thick and tight. They have a nauseating odor, even from a distance. They do, however, protect the wearer from the jagged edges of rocks and keep the wearer dry, though some would rather go barefoot than wear them.
No special bonuses.
