The saves part isn't really an issue,.. I would just kind of ignore that part for the NPC's and just do my usual with GroupCheck. As far as the spell slot thing... And I'd be lying if i said I was absolutely sure my players were religiously deducting from their sheets,.. but they've been pretty awesome with the honor system concept, and I usually track what they use during a session and check after the sessions. It makes a little more work for me sometimes,. but I find that they are really good about deducting their own and knowing what they have available. Somehow I think that's a part of the "mechanics" of the game that they enjoy,.. the keeping track of their resources, so I'm not inclined to take that away. I've not applied that kind of policy with any others and doing so now would prolly cause issues with them deducting slots.....after the script already did. If I could apply that sort of script? or policy? or app? or whatever to every spell cast, and have it auto-deduct, then I might consider it. But, I don't think that kind of application exists and making them guess which are doing it automatically and not... might just cause more issues than the value of ease that the automaicality (<--not sure that's a word) of the function provides. My players aren't perfect by any means,..but neither is our game. They do however somehow,... with some interestingly subtle tacticity? (<--not sure of that word either).. but they check each other. We often have commentary like... "are you sure You can do that?" or "didn't You just use Your only 5th level slot"... (they are all 9th level currently) or... "aren't You already concentrating on somethin else?" So... i don't think,.. at this point at least, I'm inclined to have it have to see if there's availability or auto-deduct anything.
