Not looking for questions related to my competency as a DM. Looking for possible answers to my problem.
I believe that comment was directed at Jdvn's poor treatment of classes and characters who create items.
As for how I would handle this ...
Here's a quick Excel sheet she can use when crafting her items.
It works thusly:
You're creating a 10th-level Artificer. Enter 10 into the Artificer Level field. The values calculate, and say that, over the course of her artificing career, she's accumulated a total of 1,600 Craft Reserve points.
Since she gets Scribe Scroll at level 1, she could conceivably have spent all 1,600 points on scrolls. Since she didn't get Craft Magical Arms and Armor until level 5, she could not have spent any points from levels 1-4 on A&A; accordingly, she can only spend a maximum of 1,400 points on A&A.
Let's say she wants to spend 100 points of her craft reserve on scrolls. Enter 100 in the Spent field next to "Scrolls." The spreadsheet assumes that you spend them in the most opportunistic way, so the first 20 points on scrolls come out of her 1st-level Craft Reserve. The next 40 come out of her 2nd-level Craft Reserve (affecting the maximum she can spend on potions) and the final 40 come out of her 3rd-level Craft Reserve (affecting the maximum she can spend on Wondrous Items.
Now, let's say she spends an additional 100 points on wands. Wands are available at 6th-level (check the Errata

). Therefore, she starts spending from her 6th-, 7th-, and 8th-level Craft Reserves. This flows back and reduces the total amount she can spend on scrolls, potions, and other lower-level items.
The Craft Reserve Remaining field tells you how much, of your current level's Craft Reserve, remains unspent. Unfortunately, it doesn't work quite yet. I'll keep hammering away on it.
Ignore any value less than 0.
I also don't have any idiot-proofing in this spreadsheet. I allow you to spend more than you actually can (for instance, there's nothing stopping you from entering 1,000 for Rods, even though, at 10th-level, you only 700 to spend on Rods).
I also force you to determine the XP cost of the items you want to craft on your own.
If you've got any questions, feel free to ask!
EDIT: OK - the current Craft Reserve calc is now working. It tells you how much of your last level's craft reserve is remaining, given the amount of XP you've laid out as spent.
Tada!
