Conqueror's Crusade

Violently arcing your weapon, you rush across the battlefield with a near unparalleled might.

After choosing up to three creatures that are all reachable with a total movement distance of 60 ft., make a melee attack against each target. On a hit, the target takes 8d10 force damage. Any creature whose space you pass through to plot a path to your target creatures must make a Strength saving throw against your spell save DC or be knocked prone and pushed back five feet. Regardless of whether the creature succeeds or fails this save, moving past them in this way does not provoke opportunity attacks. 

The spell ends after you have make your attack against the final target. The sixty feet movement provided by casting this spell is in addition to your innate movement speed, but the latter cannot be used to further the distance travelled during casting.
