Ambakh-u-Marad ("Destroyer of the Dead")

You gain a +2 to attack and damage rolls made with this weapon.

When you hit a fiend or an undead with this magic weapon, that creature takes an extra 14 (4d6) radiant damage. If the target has 25 hit points or fewer after taking any damage from this weapon, it must succeed on a DC 17 Wisdom saving throw or be destroyed. On a successful save, the creature becomes frightened of you until the end of your next turn.

By uttering its command word "Bektu," this warhammer can shed bright light in a 20-foot radius and dim light for an additional 20 feet.

In the heart of the ancient dwarven kingdom of Dhur-mal-din, nestled deep within the Bloodtree Mountains, the legendary warhammer Ambakh-u-Marad ("The Destroyer of the Dead) was forged over 2,500 years ago.  It's creator's name lost to the mists of time, the weapon was born from a dire need to combat a fiendish horror unleashed in the depths of the dwarven homeland.

Created from star-fallen iron and with consecrated mithril, the hammer is infused with radiant runes etched in the hammer’s head.  Legends say it was tempered in holy flames in the sacred forge of the Temple of Thorin, granting it unparalleled potency against undead and fiends. Its haft, carved from ironwood from the distant Angyari Plains, ensured an unbreakable grip for its wielder.

The hammer passed through the hands of Dhur-mal-din’s greatest champions, each hero seeking to rid the dwarven halls of this demonic scourge.  During the Fall of Dhur-mal-din, the hammer was lost in the chaos.  Where it lies remains a mystery to this day.

Proficiency with a Warhammer allows you to add your proficiency bonus to the attack roll for any attack you make with it.
