End Them Rightly

End them rightly, one might say - and you certainly do plan to. From the hilt of a spectral shortsword a small mote of energy begins to glow brightly.  It grows in size and swirls with arcane magic with each second passed, and soon enough, it leaps from its post at at the sword's hilt, ready to strike.  You point at a target within range, sending the sword's pommel sailing through the air to meet its mark.  Your chosen target takes 1d4 force damage from the pom of your phantasmal weapon, and the sword left in its wake dissipates into a shower of silver sparks. 

At Higher Levels: The spell's damage increases when you reach certain levels in your class; 2d4 at 5th level, 3d4 at 9th level, and 4d4 at 13th level.
