Sword of Elemental's-bane
This sword's blade is a dull blue-gray and is always cool to the touch.
This magic longsword (one-handed martial melee weapon, 1d8 slashing damage, versatile 1d10) deals an additional 1d6 force damage to any creature of the Elemental type.
Defeat four challenging creatures, each associated with a different one of the four elements (fire, water, earth, and air).
This blade was forged in the Draconic Sultanate for the dragonborn paladin Darahi during the Great Crusade against the Efreet.
