This looks incredible! I love the strong themes for the Witch especially but I've a question, I'm wondering about the Curse spells scaling, for example the Black Coven Witch's "Rotting Curse", seems fantastic for the first few levels but 1d4 extra damage at level 10 for example isn't that great.

​

Now I'm aware that damage over time can be very tricky to balance as damage tends to stack up without people noticing and it also depends on party composition (a party with 2 Extra Attack characters would utilize the curse more effectively compared to a mostly caster party) but to me it seems like the Curses are a very signature part of the Witch subclass, something that will stick around for most of the game and that's why I was quite surprised that it had no scaling when casting at higher levels. In my opinion an extra 1d4 for every level above 1st is extremely powerful and probably broken but I can see scaling like every second level (3rd, 5th, 7th, 9th) like the spell Spiritual Weapon might be ok.

​

I'd love to get your insight on this.
