§ sharken caverns

Potentially the most dangerous place in all of Azeno, Sharken Caverns is full of poisonous Pokemon, along with a nasty radiation that can cause people to fall ill if they stay long enough. Don't worry though, to become seriously ill, you'd have to stay in the caverns for weeks. If you start to feel ill, you could always go to the Giant Sinkhole, which is easily reachable from any area of the caverns. The sinkhole doesn't have any radiation, so it's a great place to recover.

Due to the radiation, Pokemon that aren't Poison-types can't live in the caverns. Just like humans, they fall severely ill if they stay in the caverns for weeks at a time. That's not the only worry for your Pokemon though, as they also have to deal with the potential of being poisoned by one of the many wild Pokemon in Sharken Caverns. You might want to bring a few antidotes with you, just in case.
