Glorified Mercenaries: The Rebootening

SpoilerShow

For the record, most noncombat tasks (without an opponent) I'm going to go based on a simple little challenge rating table I've got mocked up, where 3 is "easy even for a rube," spmething around 9 is "starting to get a bit tough for those with prior training," and 18 is "extraordinarily difficult even with experience."

In this case, for Naisse identifying the potions just by eyeballing them, I'm going with a challenge rating of 11, if only because... I mean all she's doing is looking at them.
d10 (2) + INT bonus (3) = 5...

Kairui would get a challenge rating of 7, because it’s a plausible and efficient solution. However, I’m applying a conditional +3 to the challenge, so if he didn’t crack 10, the fluids would all swirl together, making the whole thing pretty useless.
d10 (8) + INT bonus (5) + Skill Bonus (1) = 14!

(Side note: I considered counting it as Luck instead, since it's more banking on the animal's reactions than your own cognition, but it's moot because the resulting 11 would still eke out a victory over the mighty ten.)

Naisse: They're pretty brightly colored, like the type of chemicals or potions you'd see in a cartoon. You're fairly sure this was achieved via food coloring, and done solely to make it easier to keep the different substances straight.

Kairui: The fluids, thankfully, remain separated, and the birds and insects quickly slurp up all the fluid (with the exception of the poisonous fluids, which it turns out were red and light blue – these they quickly learn to leave alone).

Sylvain nods and takes some notes, then waves the group over to the ditch which imprecisely bisects the garden. Approaching it, you can see it’s fairly deep, and quite wide at that – there was a good deal of effort put into digging this thing out. A concrete floor has been set up at the bottom, with frowny faces, skulls-and-crossbones, little pointy things, etc. having been scrawled into it while the cement was still wet. More professional inscriptions - some kind of sigils, actually, by the looks of them - appear to have been carved into the edges after it had set.
