Magical Item – Legendary – Weapon of Thunderbolts – 100,000 gp
- Standard: Usually found as a Maul, can actually be applied to many other types of weapons at the GM’s discretion. You gain a +1 bonus to attack and damage rolls made with this magic weapon.
- Requirement: You must be wearing a belt of giant strength (any variety) and gauntlets of ogre power to attune to this weapon. The attunement ends if you take off either of those items.
- Attunement: While you are attuned to this weapon and holding it, your Strength score increases by 4 and can exceed 20, but not 30. If you are attuned the hammer has 5 charges. While attuned to it, you can expend 1 charge and make a ranged weapon attack with the hammer, hurling it as if it had the thrown property with a normal range of 20ft and a long range of 60ft. If the attack hits, the hammer unleashes a thunderclap audible out to 300ft. The target and every creature within 30ft of it must succeed on a DC 17 Constitution saving throw or be stunned until the end of your next turn. The hammer regains 1d4 +1 expended charges daily at dawn.
- Giant’s Bane (Requires Attunement). When you roll a 20 on an attack roll made with this weapon against a giant, the giant must succeed on a DC 17 Constitution saving throw or die.
- Relic: If you are a Dwarf and attuned to this item, you gain a +2 to Charisma skill checks in relation to dwarves, gnomes or giantkind. And your Constitution is increased as well as your Strength.
