So, hypothetical question for everyone: How difficult would it be to kidnap your character?
Not how difficult YOU would make it, but how difficult it would really be.
Lessee... normal boring human with no HEUG GAI or mastery of martial arts that borders on the supernatural? Probably pretty easy... if they could catch me.
Therein lies the problem. My character is usually the one kidnapping
other people. So before they could do any kidnapping they'd need to find and properly ambush him. Getting away is a lot easier than fighting back most of the time as well.
As far as kidnap and hold, as Vivi brought up... well, that depends entirely on how you're intending on detaining him. The best option would be in a completely sealed room with no actual guards posted, because human presence means human error.
