You brandish the weapon used in the spell's casting and make a
melee attack with it against a target you can see within the
weapon's reach. On a hit, the target suffers the weapon attack's
normal effects, then becomes sheathed in an aura of volatile wind
until your next turn ends. If the target moves or is hit by another
attack before then, they must succeed a Strength saving throw or be
pushed up to 10 feet in a horizontal direction which you choose
when you cast this spell. The spell then ends.
Alternatively, if you move at least 20 feet in a straight line
towards the target immediately before casting this spell and then hit
with the attack, you can instantly push the target. They must
succeed a Strength saving throw or be pushed up to 10 feet away
from you. The spell then ends.
This spell adds damage to the initial attack when you reach
certain levels. At 5th level, the attack deals an extra 1d8
bludgeoning damage to the target on a hit, which increases by 1d8
at 11th level (2d8) and 17th level (3d8).
