Minecraft – How to get custom (non-player) heads in minecraft 1.10

Create scoreboard wSkull: scoreboard objectives add wSkull dummy

[1]Repeating command block: scoreboard players set @a wSkull 1 {Inventory:[{Slot:103b,id:"minecraft:skull",tag:{display:{Name:"Leafy Headdress",Lore:["[Rare] [Quest Item]","Some irritating thorns poke out of it."]}}}]}

[2]Repeating command block: execute @a[score_wSkull_min=1] ~ ~ ~ [command you want to happen when the custom head was worn]

At [2]Repeating command block, you can do multiple of these if you want alot of things to happen whoever wears your head.

Slot:103b locates where the helmet should be put when you want to wear it inside your inventory.

Might I suggest this website that will help you to get /give commands for specific heads you want off a huge collection of heads, and you can submit custom heads and get the code anytime.

Here is an example, this command will always give the same head and isn't affixed to anyone's skin.

/give @p skull 1 3 {display:{Name:"Phoenix"},SkullOwner:{Id:"a25967e7-82fd-4594-9650-473e3b99d453",Properties:{textures:[{Value:"eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvM2Q4NjA3MjFkMzZiYjliNzllZWY3ZTM5MGQzYzQ4MTRhZTU1MDhhODkyOTE5ODI1OWJkMTgyYmY3NjE4MGI1In19fQ=="}]}}}
