Axe of the Storm King

This legendary axe was once used by a clan of Goliath warriors who lived atop one of the highest mountains. This mountain was in a never-ending storm, a blessing from their god. However, the tribe has since faded from the mountain, but the storm and the axe, still remain, guarded by the god's blessing.

You have a +3 bonus to attack and damage rolls made with this magic weapon. In addition, it deals an additional 1d6 lightning damage to any target it hits.

This weapon has the thrown property (20/40). If you throw it as part of an attack action on your turn, it returns to your hands at the end of that turn, provided that you have a free hand to hold it. If you don't have a free hand it drops to the ground directly in front of you.

You have resistance to thunder and lightning damage while attuned to this weapon

As an action while holding the Axe you can cast the Thunder Step spell at 5th level from the Axe (DC 17). You regain the ability to use this when you finish a long rest or when you take 20 or more lightning or thunder damage in a single turn (The spell cannot be added to the item as it's purchased content, so you will have to add the spell manually.)

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