Really need this honestly. One Firebolt is pretty much 1d6 + (Unavoidable) 1d4 from the fire ground spawning + (Unavoidable) 1d4 at start of turn since they're standing in fire + 1d4 if the fire isn't put out before the start of their next turn. You've hit someone (and possibly others) with a 1d6 and a full 3 shots of magic missile using a CANTRIP.
Enemies rarely stay in just one point however
The problem is they've already taken the 1d6 + 1d4 from the initial cast and at the beginning of their turn before they can even move they take an additional 1d4 from the fire ground. If they move and cannot put the fire out they take an additional 1d4 because of lingering burn damage they had because of the fire ground they were forced to get hit by.
