Hammer of Zakan

Weapon Unique, Magical, Heavy, Versatile Rare (this item requires attunement) [Must be earned by overcoming the trial of the earth deity elder elemental (Zaratan).]

Earthen Kanabō with large, very hard, jagged obsidian stones as spikes. If attuned: bonus action, touch, with a thought cause the rod to become magically fixed in place. Until you (the owner/attuned) choose to touch and release it, or you go unconscious, the rod doesn't move, even if it is defying gravity. The rod can hold up to 8,000 pounds of weight. More weight causes the rod to deactivate and fall. A creature can use an action to make a DC 30 Strength check, moving the fixed rod up to 10 feet on a success. +1 to Attack Rolls and Damage dealt with this weapon. Draws its power from the earth deity elder elemental (Zaratan), and returns to that deity, disappearing from the material plane, if you die or become unattuned to it.
