Earth Hammer was one of the weapons recovered from the underwater Kraken lair in the Goblin Tooth Mountains. It has strange abilities unrecognised in current magical weapon archives. Particularly the thundering damage it performs with each strike. Bannockburn Dranik suspects the weapon may also be intelligent, but it would require more powerful divination magic to determine this.
