Tormented spirit

In Torment league, Tormented Spirits are the spirits of tormented criminals that yield their ill-gotten gains when slain. Eager to protect their trove, these spirits flee when encountered and imbue nearby monsters with dangerous powers, which improves their item drops. It's also possible for spirits to possess rare and unique enemies, greatly increasing their threat (and value!) to treasure-seeking exiles.

The various spirits have differing modifiers that they themselves possess as a spirit, in addition to effects that they bestow on normal and magic mobs that they touch, as well as a powerful modifier that they grant to any rare or unique mobs that they possess. Any mob that is bestowed or possessed by a spirit gains a modifier (Spirit's Touch/Grip) based on the spirit that bestowed them, in addition to some slight increase to movement, attack and cast speeds, as well as significantly increased IIQ and IIR. In the case of full possession, there seems to be guarenteed rare drops involved, but this has yet to be verified specifically.
