This magic weapon grants a +1 bonus to attack and damage rolls. Giant’s Bane: You must be wearing a belt of giant strength and gauntlets of ogre power to attune to it. If either is removed, attunement ends. While attuned and holding the weapon, your Strength increases by 4 (max 30). When you roll a 20 on an attack against a giant, it must make a DC 17 Con save or die. The hammer has 5 charges. You can spend 1 charge to throw it (range 20/60 ft.). On a hit, it creates a thunderclap.
