Divide Weapon

When cast, Divide Weapon takes a weapon within sight and splits it into two of a similar smaller weapon decided by the DM. Example, a great sword would be divided into two shortswords, a a shortsword would be divided into two daggers,  a greataxe would divide into two handaxes. If there is no appropriate weapon smaller version of a weapon then the DM takes an appropriate weapon from reality and decides its damage. If you physically cannot get a smaller weapon without the smaller version being useless then the spell fails (example, there is no smaller version of a dagger and a needle wouldn't be very effective in combat so the spell would fail). When the spell is dispelled then the two weapons fuse back into its original form.
