My apologies for my poor phrasing, the fact that other casters will often have a free bonus action was irrelevant. My point was that even if it only occurs on Dragon Sorcerers, Firebolt + a good shot at blinding an opponent seems a touch too strong for someone to be able to do without expending resources. If we did want to consider other classes using it though, it can't be taken via Magic Initiate but it is only a one level dip in to Sorcerer to take it that way which could be an added bonus for casters that were already planning to dip for Metamagic, proficiency in Con saves, ect. Still probably not game breaking though, so maybe allow it if your player has their heart set on it and isn't likely to optimize this character to the limit.
Well no one's taking it or using it. I could make it a DM exclusive so it won't pop up to often.
