Produce Flame is now a Bonus Action, but the attack portion is still an action. The range of the light has increased to 20 feet, and the range of the attack has increased to 60 feet. Also, the attack can now target creatures or objects. (this is the new option, and only option. Just Produce Flame, no old version).
— Changes due to 5.5
I really do try to make most of this original, but since Forgotten Realms is an integral part of the world I can't help if anything is used without formal permission, but is still "fair use" as I am just using this for my private games.
