Medium
The Medium mutation allows players to seek out other players' locations with their mind.
This mutation gives a +1 to Focus. You must have the Clairvoyance mutation before you are able to obtain this mutation.
This is one of the mutations that Empath requires; the total mutations needed are Medium/Blink/Flight and Swollen Brain. Please note that you do not need all three movement mutations to become an Empath. You only need one.
By seeking out a player, you can find out their general location; if your focus is high enough, you can accurately locate where they are. You still have to be careful, however; if the player you are seeking has a high Focus, they will be alerted that someone is seeking them, who is seeking them, or detect where they're being sought from, which can potentially be dangerous. Seek with caution!
