Here is a bow i made today, based it on the an idea another user had for an elemental bow. i took the basic idea and tried to expand upon it

This shortbow is an elegantly carved weapon made of mahogany. When using this bow and before an attack is made, you may elementally charge your attack. Doing so adds one of the following enhancements to your attack. The bow has 6 charges, expending 1 charge per use and regaining 1d4 2 charges after a long rest.
