I'm trying to make an item that gives one additional spell slot at the lowest level.  It is a charged item and it grants one spell slot of the lowest possible level for sorcerers. 

I'm having difficulty finding a way to make it happen with the way the homebrew system parameters and right now it's just an item that we will 'hand wave' use when we use it.   I'd love to have it present as an option on the online character sheet.

I know there is the thread to ask what new features they should add; I searched on that thread and this forum and didn't see anything about spell slots; before I ask on that thread, I'd thought I would ask this forum if anyone knew a way to do that.  If no, then I'll go post and ask on that thread.

Thanks in advance for your help

Add charges. Rephrase it "When you cast a spell using a first level spell slot, you may expend one charge instead of expending the spell slot."

There is currently no modifier to add spell slots to a character. People have requested it though.

 That's a clever idea I had not considered until now!  Thanks!

I guess I'll also be one of those people.

There are a lot of staves that have these effects as well as pearl of power and rod of the pact keeper, maybe make some adjustments to those

I have made a magic item similar to what you want, feel free to use it.

That's a very good idea.   I've been trying to think of a way to solve the same problem.
