Griffie is checking on the Winterbite Mint, harvesting shears out.
Cornelia comes by with a cart of sealed containers "Are you ready to begin biological testing?"
"Yep! I'm ready to expose plants to positive energy in the lowest dose that I'm used to distributing."
Cornelia sends in a sample of engineered chamomile.
Griffie positions themself near the sample. "Ready to perform the first exposure when you are."
Griffie targets the chamomile sample with Stabilize.
"I'm not seeing any result with my senses either. This result would be unsurprising with plants from my own world, save for how this one appears lifeless. The amount of energy I used there is significantly greater than the background amount I'm leaking, so I think we can be less concerned about that."
"All right. What effect next?"
"I could prepare several instances of that disease-diagnosing spell, and we could consider this plant a baseline plant sample?"
"No, we should get a fresh one for a baseline. We have plenty."
"Alright. Rest of the plan work for you?"
After a protocol discussion, spiritless chamomile, in numbered opaque boxes, is added to Griffie's quarantine facility.
On analysis, the chamomile can be divided into several groups.
Plants which are presumably baseline samples. These have more extremely minor diseases than Griffie is used to seeing, but are overall healthier than plants cultivated in Suaal by any non-druid. Druids notably weaker than Griffie could wipe out such minor diseases in fairly broad areas, enough to eventually give the diseases no local reservoir. Presumably this world doesn't have low-level druids doing plant care circuits.
Dehydrated samples, which seem unusually healthy, as dehydrated plants go. Perhaps they were dehydrated recently, or perhaps there are fewer opportunistic diseases around.
Samples which, in addition to the baseline diseases, are in the early stages of a few types of fungal disease. The fungal diseases look rather strange, and also like they would be trivial to cure if only Griffie had some quite exotic substance on hand. On further consideration, remarkably trivial, diseases usually aren't quite that responsive to any medicine.
If the positive-energy-exposed plant is present, Griffie can't discern it from baseline.
Without opening the boxes, Griffie divides the plants into categories and describes them.
Cornelia blinks. "Correct, yes. There have been various projects to try to clean up omnipresent diseases, including those in the standard genome for the plant… it sounds like your effect is at least somewhat discriminating, though I still want to check that it doesn't kill our lifeforms. The offspring of those who have diseases removed by your effects, are they healthier?"
"Yes. There's a reason that people are particularly interested in receiving medical attention when pregnant."
"If it is safe, I would like to be able to examine the difference between a baseline plant and one which has had your remove disease effect applied."
"It seems like it would be safe to me. You may also wish to see the effects of untargeted positive energy attempting to heal a plant, in the same quantity as 'Remove Disease' uses?"
"That sounds preferable, yes. Could I get two samples of each of those?"
"I could, but that will cut into my ability to perform other spell tests today, do you think you could make do with one sample of each for now?"
"One of each for now then." she says, and sends in fresh samples.
Griffie casts Remove Disease on one sample, and a well-calibrated modification of Cure Light Wounds on the other.
Cornelia takes the samples, carefully keeping them in quarantine, and examines them in her lab.
Griffie uses the time to talk to someone else about beacon text in Celestial and Draconic.
Eventually, Cornelia returns.
"Well, no nasty side effects on either yet. The untargeted effect is… interesting, and honestly has me a bit concerned. Are you capable of making it stop if you do larger ones in the future?"
