Unsure if this is a bug or if the functionality just isn't possible. I have been trying to create an item that has multiple spells and each spell consumes a different amount of charges on the item. I have looked at the Staff of Healing and want to emulate its functionality but with different spells and details.The item I am currently working on is this: Ignis Clavis I have tried numerous changes to imitate the effects of the spells but am unable to have a spell consume multiple charges with a single use (I also would like the know if the ability the Staff of Healing utilizes with Cure Wounds is possible - the level you cast the spell at = charges consumed).

Set minimum charge to the level of the spell you want the spell to be cast at, at lowest. Set maximum to the maximum level the spell can be cast it.

A Staff of Power, for example let's you cast Fireball at 5th level only, so it would have both min and max charges set to 5.

While an item like wand of magic missiles has the option of casting the spell at 1st level up to 7th level. This would be min charges at 1 and max charges at 7.

I would recommend going to make a magic item, instead of making from scratch, choose to make a copy of an existing item with a similar feature (like Staff of Healing), you can then see the modifiers and how it's made. This can only be done for items in free Basic Rules or those you have bought - it will not work for those shared with you via campaign sharing.

Thank you for the response, I have tried those alternatives but the spells only consume 1 charge no matter the min/max values. They way you explain it is the exact way I expect the items and the values to work but nothing has worked - I have even copied Staff of Healing and altered the spells while keeping the values the same but that was not successful. It is encouraging seeing as this functionality should be working for Homebrew items. Perhaps it is just a bug currently? I am seeing a decent amount of Homebrew and content sharing concerns as of late.

UPDATE: I tried editing a copy of the Staff of Healing again. I entered "test" in the item description to be sure it was updated when I added the item and the only other thing I changed was Cure Wounds to Flaming Arrows (did not touch the values). When I added it to my character the text was updated but the spell is STILL Cure Wounds! WHAT?

Hello! Taking a look at the homebrew item linked above, I'm not seeing a "minimum charges" entered for the "Flame Blade" spell. If there is no minimum entered, the system will assume it is the lowest value (no minimum). 

If you wanted to, for example, have the "Flame Blade" spell use 2 charges when cast, you would set the "Minimum Charges" to 2. If the spell cannot be cast at a higher level than it is usually cast at, you would set the "Maximum Charges" to 2 as well. If you wanted the player to be able to "upcast" the spell at a higher level, you would want to set the "Maximum Charges" to a higher number than 2, with each number above 2 adding a higher level the spell can be cast at.

Thanks for the response! I did understand that functionality but from what I'm seeing, the spells and their Min/Max values are not updating quickly at all. It seems whatever I last leave it at, the next day it will be represented correctly on my character sheet. For instance, I've just changed the spells on my custom item, the amount of charges, and the description. All that is changed when I add it to a character is the description and the amount of charges in total on the item. The spells and their Min/Max values have not changed at all.

I've also noticed I cannot add any of my Homebrew Items to the characters within my campaign I am DMing. (there is another thread on this issue, though, but wanted to mention it again). From everything I'm told, I have everything needed in order to share Homebrew items.

I've been playing around with this spell charge system for upcasting spells by using more charges, and I've been trying to apply it to some homebrew races without success. Does this system only work for items or is it possible to apply it to races and subclasses as well?

It currently only works for Items.
