THIS needs to be a thing!
I would love a lot to use PK in Minecraft...
Also there should be PK Beam, but you can't learn it if you learned PK Rockin'.
There should be Three User Options, like:
PK Users: Learns PK by leveling up and can use Mirror via Mu Training. Uses Melee.
Gadget Users: Can use Bottle Rockets and can repair Broken Items to use it. Also they can Spy to know an Enemy's type and weakness. Uses Guns.
Weapon Users: Can use Strong Melee weapons that other Users can't.
Also there should be a Party system (4 players max.) if a party member uses PK Teleport, all the Party teleports too.
