Allows you to learn the invisibility spell. This is the special spell for rangers. Casting this spell causes you to turn invisible for 31 to 45 (more) turns. There is always a spellbook of invisibility generated in a chest on the middle level of Vlad's Tower.
This is not a very useful spell. It might be useful if you only want temporary invisibility, to gain its ability whilst still being able to enter shops. However, since even if permanently invisible you can still enter shops using a mummy wrapping or teleportation, permanent invisibility is often a better option, and probably easier to obtain than the spell. Rangers are very unlikely to be able to make use of this special spell of theirs before they find a mummy wrapping and a means of permanent invisibility.
One niche use of this spell is to cast it before eating a stalker corpse; this causes the invisibility to become permanent and also gives an important permanent see invisible intrinsic. This is only necessary once per game, though, and any other source of invisibility (potion of invisibility, wand of make invisible, ring of invisibility, another stalker corpse, etc) works just as well.
