Wayfarer Inn
Three floor dungeon.
When you encounter a tuxemon, they are infected with Spyder Bite. They "Shiver" instead of using a technique 1/4 of the time.
When you talk to the Nurses and Scientists on the second floor, they reveal that they had to quickly abandon the lab for unspecified reasons, but they have snuck in to find some of their stuff. They despair at how wild tuxemon have wandered in, and "been infected by ... well, I shouldn't say".
When you talk to the ENFORCERS on the third floor, they also hint that something's happened, and they talk about "quarantine" and "centralised checking of DNA" and "the virus".
Booster Tech: When given to a tuxemon, it evolves (if it evolves via Booster Tech). When given to Botbot, it evolves into the secondary form of your choice, but continues to hold the Booster Tech. When the Booster Tech is taken off it, it de-evolves. (So you can vary which evolution route it takes).
