Jah is one of the most valuable high runes in the game. Online, it is more common than
Ber runes despite being higher on the list of runes. It's a part of many top level runewords, in particular
Enigma.
Every single one of its runewords are viable in some fashion, though
Famine is fairly weak in comparison to other options. It is also popular for putting into Helms and Shields for the health bonus, further increasing it's value.
In single player, it's one of the most difficult runes to get because it is not retrievable through
Lower Kurast runs, while being one of the most important runes because it enables classes other than Sorceress to be able to
Teleport.
