Reboot/Corrupted should be merged into Hacked, and Possession left the same.

However, how can we make the two things different?

Possession can attack own team? Hacked can attack just himself?
Possession can lose the possessed monster 25% stamina for each hit? Hacked can make the hacked monster get double damage?

There is also a status effect such as "apply random problems to target monster", and maybe this should be Hacked?
