Hey there.
I was wondering, is it somehow possible to turn off the True PvE protection for seperate users? Kinda an outlaw system where one player can be killed / raided by everyone else while not being able to do the same?

hi, no, you would need to use a plugin specifically for that. it simply requires too many variables to be an option.

my Abandoned Bases plugin could do this by using the /sar command on that base
