Flame Ambers
The legendary flame ambers are one of the most powerful magical items known to exist. A single such amber, used by a skilled mind, can slay several hardy men. Ten thousand, it is said, would allow an entire city to be annihilated.
Fortunately for the peaceful minded, these items are difficult to acquire. They are formed through a special totem ceremony involving a red amber and essences of flame. Red ambers have only been found by miners who have stumbled into unpredictable extradimensional rifts.
During times of great chaos in the Nexus, flames burning deep within the earth extend closer to the surface. Occasionally a blast of flaming vapor will erupt through the soil. An aware and quick collector can use a bottle to capture some of the vapor.
