4. Hammer of Thunderbolts

The Legacy of a forlorne master-smith, this weapon gives a worthy wielder unparalled strength. 

The Hammer of Thunderbolts was forged by a Dwarven smith as a gift for his son on a campaign. They fought a war against Giants and Ogres, which the smith hoped these weapons would turn for the better. His son was slain and in grief, the father donned the armor and weapon he had made for his son. He died a noble death in service of his kin.

You can only wield the hammer if you are wearing Gauntlets of Ogre Power and a Belt of Ogre Strength. When attuned the weapon raises the cap on your strength to 30 and adds a +4 bonus to your strength score. This makes it on par with the best weapons in the game despite the given +1 in combat. Additionally when thrown the hammer can create a sonic boom, stunning everyone within 30 feet of the hit. A powerful weapon for ruthless warfare, there are few stronger forces in the realms.
