Zamorak mjolnir

The Zamorak mjolnir is a two handed weapon. To obtain one, either complete the Enchanted key miniquest or trade with another player. However, you can only receive one Zamorak mjolnir during the Enchanted key miniquest.

As its name implies, the Zamorak mjolnir is affiliated with the god Zamorak. It is tipped with Zamorak's symbol, an upside down 'M'.
