I'm going to make an OP armor set using commands for singleplayer XD and yes, my in game name is SleepyString, so, for the first part, to get the boots, go on a creative singleplayer world, type /give <name> minecraft:command_block , then right click it, copy this command:
/give @p diamond_boots 1 0 {
display: {
Name: "Sleepy's Boots",
Lore: [
"The Power Of These Boots Flow Through you"
]
},
AttributeModifiers: [
{
AttributeName: "generic.maxHealth",
Name: "generic.maxHealth",
Amount: 208,
Operation: 0,
UUIDMost: 92914,
UUIDLeast: 893314
}
],
ench: [
{
id: 0,
lvl: 5
},
{
id: 1,
lvl: 5
},
{
id: 2,
lvl: 5
},
{
id: 3,
lvl: 5
},
{
id: 4,
lvl: 5
},
{
id: 7,
lvl: 5
}
],
HideFlags: 1,
Unbreakable: 1
}
then Ctrl+V (paste) it into the command block and power it. :
