A toktz-mej-tal (also known as an obsidian staff) is a two-handed staff used by the TzHaar-Mej, and can be obtained as a very rare drop from them. Level 60 Magic and Attack is required to wield it. As well as being able to cast Magic spells, it can be sufficiently used as a melee weapon due to its attack bonuses. It is the only staff to require two hands to equip.
Ten of these are used to build an obsidian fence at level 83 Construction in a player’s Superior Garden.
