I have a 3pp cantrip that is a Dex save or be blinded. It's also a bonus action to cast.
It's also a Sorcerer spell with the option to restrict it to Dragon Sorcerers only.
So you can try and blind someone and follow it up with a cantrip with advantage to hit.
I think it's OP as hell. But Sorcerers are often regarded as weak.
Blinded for how long? Just until your next turn? End of your next turn? Start or end of their next turn?
