This mythical war hammer has been magically imbued with the furious nature of storm to smite its wielder's foes asunder.

You gain a +3 bonus to attack and damage rolls made with this magic weapon. It has the thrown property with a normal range of 20 feet and a long range of 60 feet. When you hit with a ranged attack using this weapon, if the target has taken lightning damage since the wielder's previous turn, it deals an extra 2d8 lightning damage. Immediately after the attack, the weapon flies back to your hand.

Immovable Object
When attuned to this weapon, the wielder may use an action to cause the hammer to become magically fixed in place. Anyone not attuned to this hammer must succeed a DC 25 Strength check in order to move it.

Tempest Shield
Whosoever wields this hammer gains resistance to lightning damage, or immunity to lightning damage if they are for any reason already resistant.

Storm's Eye
When a spell that deals lightning or thunder damage is cast by the wielder, they can, as a bonus action, throw the hammer to a location within its throwable range, and cast the spell through the hammer. The hammer flies back to its owner's hand after the spell has been cast.

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