A Tale of the Realms
Sword of the Dales
The Sword of the Dales is a long sword +3 made of silver and inlaid with gems in its pommel. It glows with a soft blue radiance. The Sword unlocks chains and manacles within 30 feet if the wielder speaks the word merrydale. The Sword grants the wielder the ability to breathe water (as the spell water breathing) once per day.
The weapon is rumored to have additional powers, but no one knows what they might be. Even identify and similar magic are unable to discover the swords secrets.
