My D&D game I'm in is all spellcasters. Arcanist, Sorcerer, Wizard, and Bard. There's set-backs, but it's a good group. It doesn't take an all-spellcaster game to need more magic-based goodies for the game. That's where Hexbound comes in. It's a new witch-based supplement that's up on Kickstarter now.
From the campaign:
Hexbound is a witchy supplement for 5th Edition. It gives both players and game masters all the necessary tools to add the magic of witchcraft and witches into their games.
We've designed it to be as easy to use as possible for both players and game masters. All the content in the book, from witch subclasses to witchy adventures, can be used as an addition to your existing campaign or as the bedrock for a completely new witch-themed adventure!
The book offers content for both players and GMs alike, with new witch subclasses, spells, familiars, and backgrounds as well as ready-to-run, fully illustrated adventures, magical items, new creatures, and more!
The campaign's more than 4x funded with 29 days to go.
