Amil'Thea

 is a Oddity of equipment in Torment: Tides of Numenera.

Description
This unadorned, sturdy-looking, brown leather necklace has one silvery metallic ring dangling from it. On closer inspection, you can see that it is worn with age and has been chewed on by a sharp-toothed creature. Wearing it seems to slowly turn the most grumpy, pessimistic individual into one with a more cheerful and positive demeanor - and, strangely enough, generates a strong urge to chew shoes.
