Troll Idea: Make some Draconic Armor, make it really freaking overpowered (basically maxed out with full power), give the armor Curse of Binding, and choose a random player. Set up a trap in their base that will 1) kill them and pick up their items so that their items are safe, 2) once he respawns at his bed he will have the Curse of Binding Maxed-Out Draconic Armor forcibly put on him, and 3) use another mod to make a one-way warp to the Corner World Border at "X=±32,000,000 Z=±32,000,000" coordinates (and then have the bed trap destroy itself afterwords so it doesn't get triggered again). He cannot get back in a timely manner without dying, they do not have any potential house warps they would have had if they hadn't died to set off the trap, and they have insane god armor that can allow them to survive the self-destruction of a Chaos Island AND a full-powered Draconic Reactor Nuclear Meltdown right next to the core (albeit with half a heart) and they CANNOT TAKE OFF THE ARMOR TO DIE TO GET BACK TO SPAWN.
TL;DR make overpowered god armor DRACONIC ARMOR, give it curse of binding, kill a player, and rig their bed to give them the god armor and one-way-warp them to the corner world border (presumably the one that is farthest away from all of the bases)
You can even put up a sign on the other side saying something like "hey, I heard you needed some help with getting more powerful stuff. Here, have some god armor!" or something like that just to add to the rage. Basically, you turn invincibility into a priceless troll.
You're welcome.
