Your hatred for wizards has inspired a weapon in your orb. As a bonus action, you can direct your orb to fly over and shock a creature within 60ft. Upon being shocked, the creature must make a constitution saving throw. On a failed save, the creature takes 1d4 lightning damage and can not cast any new spells for one turn and innate abilities/actions (e.g., ghosts possess, beholder's rays, dragon's change shape) must make a DC10 Constitution to succeed. Existing spells under concentration are unaffected.
On a successful save, the creature takes half damage and spellcasting is unaffected.
Damage increases by 1d4 and charges increase by 1 every time your proficiency bonus increases (5, 9, 13,17).
Line-of-sight is not required, but the orb must be able to make it to the target within 60 feet of movement. Attacks from stealth require a stealth check and give disadvantage on the saving throw to the target.
