Great. Now, it seems at least plausible that medallions are actually enchanted with a whole bunch of spells, so the next thing to do is test stacked enchantments. She does it again, this time with the phrase "diagram or diagrams" in the incantation, then adds a durability spell to the rock and tries once more.

Her paper gets both diagrams on top of each other.

That is absolutely hilarious. She adds in "next to each other".

They escape her paper to print full size onto her desk, still in the medium of light burnination.

This is not hilarious at all! Now she needs to scrape up that bit of her desk so it looks like carelessness. It looks lame, but her parents won't think she's started deliberately burning weird symbols into her desk like, uh, some kind of mad cultist who thinks she's a shapeshifting magic user.

Okay, new tactic. Blah blah "the first diagram used to enchant this rock" blah blah blah "unless this rock has fewer than one enchantments on it".

Glow diagram. ...not stroke for stroke identical with the others she's gotten this way.

Interesting. She puts a protective layer of old newspapers on her desk under all the apparatus and similarly extracts the second diagram.

Disenchantment diagram.

Ohhhhh. It's getting the actual first spell used on the rock; disenchanting it apparently doesn't make what came before it opaque to exploratory magic. She wonders if the second numerically-based clause is getting interpreted the same way and asks for the third spell. If having two active and several past enchantments means the rock counts as having "fewer than three enchantments on it" this should do nothing; if the full history of enchantments still count as being on it then she'll probably get another glow diagram.

Nothing.

She spends a while looking up the nuances of French tenses, then changes "has fewer than" to "has had fewer than" and tries for the third enchantment again.

Glow diagram.

That's good, but she has no clue how many spells she's done on this particular rock and doesn't want to go through a pile of paper finding out until she gets to the stacked ones at the end. She disenchants this one, gets a fresh one from the yard, and makes it first glowy and then durable. Can she get the two diagrams in order one at a time?

Yes she can.

Great. In that case, she's ready to . . . email Bella with her results so far. She wants a night and a day and a second person to think of anything she might have missed before trying anything on the Tikbalang medallion.

I wonder if there's a way to more thoroughly disenchant something?

If there's not, or usually no reason to bother, you might get draft diagrams that were applied to the medallion before you get whatever's on it now.

Yeah, I'm prepared to go through a lot of paper getting diagrams until it comes up empty, and then go through and ignore anything before the last thing that looks like a disenchant. Does your spreadsheet have a mode where you put in the runes and it tells you how much of what meanings you end up with, as well as the one where you put in meanings and it gives you runes?

No, but I can make one, gimme a bit. And some test diagrams where you've got it worked out what all's in there so I can test it.

Awesome, thanks!

She attaches the invisibility, durability, glowing, and disenchantment diagrams, plus a table with the amounts of each meaning they end up with.

Someday I'm going to be able to do this in a real programming language, it's a pain in spreadsheet. Give me a few days to make super sure it's all right.

While she waits the few days, she can get caught up on jewelry orders and work on healing items a bit more. She enchants a rock with an incantation almost identical to what worked for worms: "Make this rock heal any human it touches, restoring that human to full health as though he or she was never unwell." Then she nicks a finger and pokes it.

It doesn't work at all.

She's very confused for a minute, and is about to go replicate the earlier trial on earthworms when she remembers she's not actually human. Facepalm, disenchant, try again with "personne" instead of "humain".

That one works fine.

Time for--she sighs--more experiments with self-injury. When she bites hard on her lip, hard enough to hurt a lot but not hard enough to draw blood, and then touches the rock, does it make the pain fade faster than it would otherwise?
