The Explorer's Hammer
Weapon (warhammer), rare (requires attunement)
This ancient warhammer has maze-like patterns carved in to it's head, and it's handle is made of solid oak with inset dwarven runes. The weapon was crafted by a nomadic dwarven clan, to assist in the exploration of lost dungeons.
The Hammer of Exploration has 2 charges, which are renewed every dawn. As an action, you can expend 1 charge to:
Cast the Knock spell without using a spell slot.
Locate the nearest hidden door within 30 feet of you. Once you have found the door, the hammer vibrates slightly in your hand. If there is no such door, nothing happens.
While attuned to the Hammer of Exploration, you have advantage on Wisdom (Perception) checks made to detect secret doors (including trapdoors) within 30 feet of you.
If you use the hammer to make an attack roll on a door, the door takes double damage.
A door is normally an object that was designed to be opened and closed, and is made of a mundane non-magical material. What does and doesn't count as a door is at the discretion of the GM.
