[MENTION=552]Creamsteak[/MENTION], just waiting to see if the check is successful, as I wasn't sure what the minimum for success was and Thaliss' actions will depend on whether he falls off or not.
You are correct: 1 action and one bonus action. You can also take 1 reaction. this means that you can cast a maximum of 3 spells per round: one during your turn as part of your normal action, one on your turn as a bonus action (cantrip), and one out of turn as a reaction.
Cheers,
Right, which would preclude casting Misty Step as a bonus action on someone else's turn to avoid falling damage. I think feather fall is going to be your only option to avoid damage.
For clarification, the bonus action doesn't have to be a cantrip. The limitation is that if you do cast a spell as a bonus action, the spell you cast using your action can only be a cantrip.
