Elven Bow of the Elements

When making an attack, you may choose to add
an element. If the attack hits, you may do 1d6
bonus damage of that element, and the target
must make a DC Constitution saving throw.
If it fails it, the elements hinder it.
Force: shot prone
Frost: speed halved until your next turn
Thunder: the next attack has advantage
Each element has a charge, recharge at dawn
