Downburst

Basic Effects: Exerting a higher level of manipulative control and swiftness in diverting and merging the Opal currents of Aeir, you weave them in the Aether, drawing them together with enough volatility to create a small example of a true destructive force within nature, as a sudden burst of hurricane force winds just hammer down onto the target area, flattening plant life, felling trees, collapsing buildings, shattering glass, and of course absolutely bludgeoning any creature in the area with thunderous blow. Any creature caught in the area must make a Toughness Defensive Test. If failed, they take 4d6 thunder damage and 4d6 bludgeoning damage as they are hammered to the ground, knocked Prone, as well as gaining the Deafened (1) condition, and they are Stunned for 1 round. If they succeed the defensive test, they only take half damage, and are not Stunned, though they are still knocked Prone and gain the Deafened (1) condition. Those that fail their saving throw also drop anything they are holding. The area struck by this downburst becomes difficult terrain. Structures take an additional 2d6 thunder and 2d6 bludgeoning damage from this spell-form.
