Whoever you are , you might be shadowbanned . <| sep |> First off bonus actions can only be used on your turn , if you are looking for things to do between your turns then you need to be looking for spellsabilitiesfeatures that use your 1 reaction per round . As to what a wizard has available for bonus actions it is mostly spells , a few of the wizard schools might have abilities that require a bonus action too . If you do cast a spell as a bonus action you will be limited slightly on what you can do with your action too since you can not cast two spells of 1 st level or higher on a single turn , though action surge does allow you to bypass this restriction as I recall , so you can cast a bonus action spell and then you can only cast a cantrip with your action if you want to cast a spell instead of attack or something else .
