Reason I asked is that I goofed when DMing a 3.5 session a couple of weeks ago and didn't realize/remember that the Potions of Invisibility the characters were using would have expired when they made their first attack.
I see in the SRD that potions can normally only be made from 3rd level or lower spells. Are there any exceptions or ways around this?
I don't want to undo that section of the adventure or replay that section, but I need a good explanation for why other Potions of Invisibility won't work in like these did in the future.
Ideas?
