The collective power of a Samaria great storm is focused, coalesced and intensified in the being known simply as the Greater Storm Elemental. One of the Dragyri Air Caste’s most intimidating and savage weapons, the Greater Storm Elemental is the power of a tornado mixed with the relentless momentum of a hurricane. It combines all of the abilities found in its lesser brethren, the Squalls, but with an added puissance that truly makes it greater than the sum of its parts.
