Mal

Although used in several worthwhile Runewords (e.g. Infinity, Last Wish, and Oath),

Mal runes are value-limited by the simple fact that two Mals can be transmuted into the de facto trading currency of Diablo II: the

Ist rune.

Moreover, because of the inherent usefulness of

Um runes by comparison, most players would not transmute 2 Ums into a

Mal. Instead, players will usually trade an

Um +

Pul to obtain a

Mal.
