If you want to add some interesting flavor (no pun intended) to your campaign, consider adding the Honeymage Wizard Tradition. The (predominantly) halfling wizard tradition is well flavored and pretty interesting: arcane beekeepers. They add several reskinned druid spells their list. Honestly, the only issue I have with the class is the 10th level ability seems a bit over powered. In addition to the presenting a new wizard tradition, we're also given stats for monstrous bees.
I really like this pay-what-you-want pdf. Want to know what the buzz is about (pun intended)? Check out the Honeymage Wizard Tradition + Monstrous Bees on the DM Guild site.
