When you precast it, does it use the spell slot? Or does it just add it to your reactions?
In the other game? Dunno right now. In my idea for handling the reactions in BG3? Probably have it work the way it does now except with the message part added in, so when you precast Hellish Rebuke it takes the spell slot up. Would make it easier to add to the game most likely if they didn't have to rewrite the way precasting a reaction spell works on top of adding in the message, and also removes the possible bugs of precasting Hellish Rebuke, using all your spell slots up, and the game still letting you use Hellish Rebuke anyway lol.
