While most of what Yukki said is correct, you don't need to describe how the spear is swung or thrusted. When buying a weapon-type move, any type of motion with it is included in the move. Stuff like charging it up or adding a different effect would require additional description and move slots. Also, you would be able to throw the spear, though it would only be effective within the range outlined in the Physical Strength proficiency (12 feet).

Lastly, you'll need to list the history/events right before Omni pulled you into the Omniverse.
