Minecraft wiki entry for Player_versus_Player, associated text: Let's say you're in a small guerrilla faction. Your members in your faction aren't half bad. However, the only problem is that there are a few people. They don't mine or gather too much, although they are quite skilled. The problem here is that even if they don't die much, they still do. Instead of using people that need supplies, why not make an army that purely just spawns with them? An army of skeletons is best, although zombies work too (husks or drowned are better, husks won't burn in sunlight and inflict hunger while drowned may have tridents which deals heavy damage). If you can, try to get your hands on wither skeletons, that can attack with their stone swords and still give the Wither effect, or better yet, give them bows long forgotten and unneeded so that they can shoot flaming arrows (even with unenchanted bows) and set the enemy on fire, although this may take more time to wait for them to spawn and transporting them is more difficult. Find a skeleton monster spawner, set up a network of water transportation (if you are using wither skeletons, try using lava), bring them to a certain room, with someone in there. Then, when the time comes and somebody comes to raid the base, unleash them. Such an army does not mine diamonds for you, but even so they're useful by the fact that they're easy to find and easily replaceable. Perhaps your server has a custom spawner of more powerful monsters such as vindicators, if that's so, also use them! (Make sure that your enemy won't take advantage of the monster's loot, such as the totem of undying.) One can throw a trident enchanted with Channeling and Loyalty during thunderstorms to cast lightning which makes charged creepers, zombie pigmen and witches.
