Brain Vat: cost, levels and upgrades
Short answer
The Brain Vat delays IQ fading by a day per level and makes practice mini-games pay 10% more materials per level.
What it does
Each level gives one more grace day before a mini-game starts to lose freshness, and 10% more materials from practice runs. Gold, decoys and Trial rewards are not changed.
You can have one Brain Vat per village. It's a support building: it makes nothing on its own, but it delays the fade of the IQ you built up in the mini-games.

Tips
- Worth building if you step away for days at a time: a few grace days mean your IQ is still full when you return.
- It doesn't touch your skill levels, which never drop from being away. It only slows the fade.
