We can now mass-produce Powerstones-lite, perfect for giving yourself a temporary boost when you need to blow up an enemy formation. That's the kind of thing you literally always want to have on hand Just In Case, the way we have that Ulgu powerstone and could have (if we'd thought of it) used to make our rescue operation safer. The way Mathilde just casually made up a huge pile of mushroom tea for Hubert shows exactly how I expect most magisters to react when they're kitting out their journeymen: Relatively cheap and
super useful.
The best part? Once you set up an ulgu-rich environment for the mushrooms to grow, you can probably make them
without substantial spellcaster intervention. And when you
do have the wizard support, you can apparently crank out batches in days.
TL;DR Investing a few AP in setting up production of these could probably give us a consistent stream of a few CF a turn. Or Panoramia could make a mad load of dosh, that's also an option.
