Spirit

From MUME

For another mob with the same name, see glowing spirit.

Spirits are aggressive, evil level ~11-12 mobs. They are incorporeal and cannot be bashed. Most load no items, but there are two exceptions - one spirit in a ruined castle south of Fornost sometimes loads a sombre runic book, and a spirit in a hidden cairn south of Bree loads a forest green cloak.

A spirit floats towards you and howls with an evil laughter.

It seems to be a restless spirit of an old soldier, one of its legs
almost separated from its body. The spirit is transparent and hard
to see clearly.
