Rune hasta
From Emps-World Wiki
The Rune hasta requires an Attack level of 60 to wield. It can only be obtained as a rare drop from the Smoke Demon Champion and Corporeal beast. It cannot be purchased from a Shop or made by using the Smithing skill.
The Rune hasta is a one handed melee weapon, similar to the spear. Although Hastas offer no defensive bonuses, the fact that they can be used with a shield provides more defence than a normal spear. The Rune hasta has the same stats as the Dragon scimitar.
All hastas except for the Dragon hasta can be poisoned with Weapon poison.
