In the Shadows of the Last War
You gain a +2 bonus to attack and damage rolls made with Maelstrom.
The sword has 7 charges. If you score a critical hit against a creature that has fewer than 100 hit points, it must succeed on a DC 15 Constitution saving throw or be slain instantly as the sword tears its life force from its body (a construct or an undead is immune). The sword loses 1 charge if the creature is slain. When the sword has no charges remaining, it loses this property.
This blade was upon the person of Alestair Irvallo, who sought to take it to Thrane to face destruction for its evil nature. The sword is now lost.
