I've been tinkering with an item all day but haven't been able to figure this out. How would I go about adding multiple levels of a certain spell to a homebrew magic item? For instance, I've made a wondrous item, and I want it to allow casting of witch bolt at levels 1, 2, and 3, but I cannot find a way to make that work. Anyone know the answer to this?

Attach the spell to the item and designate the casting to require charges “min: 1” and “max: 3” and give the item at least 3 charges.

Works! Many thanks.

Been doing exactly this all day and it doesn't work. Am I missing something?

What level(a) is/are the spell(s)?

I was trying to add Thunderwave lvl 1-3, but it would only cast at lvl 3. It seems to be working now, but I dunno what I did differently this time. Lol. Must have just been a glitch with the website.

Either way, thanks!
