# First it tests for the head in the chest. Then it looks for boots and tags them DropBoots
# The tag will only be added to items that match the criteria. If no boots are found, the boot stack won't be activated.
scoreboard players tag @e[type=Item,x=-254,y=42,z=-63,r=2,c=1] add DropBoots {Item:{id:"minecraft:leather_boots"}}
scoreboard players tag @e[type=Item,x=-254,y=42,z=-63,r=2,c=1] add DropBoots {Item:{id:"minecraft:golden_boots"}}
scoreboard players tag @e[type=Item,x=-254,y=42,z=-63,r=2,c=1] add DropBoots {Item:{id:"minecraft:chainmail_boots"}}
scoreboard players tag @e[type=Item,x=-254,y=42,z=-63,r=2,c=1] add DropBoots {Item:{id:"minecraft:iron_boots"}}
scoreboard players tag @e[type=Item,x=-254,y=42,z=-63,r=2,c=1] add DropBoots {Item:{id:"minecraft:diamond_boots"}}
# then if that tag exists, it sets a redstone block at the top of the Level 1 Boots Buff stack.
execute @e[tag=DropBoots] ~ ~ ~ /setblock -252 40 -68 redstone_block
##
## here, we need to add DropHat, DropPants, DropChest, and DropSword for every material of those items, followed by checking to see if that tag exists, and if it does, placing a redstone block at the top of the appropriate stack. Then we need to add four more of these, one for each buff level.
##
# placing the redstone block activates this sequence:
# first, the buff
entitydata @e[type=Item,c=1,tag=DropBoots] {Item:{tag:{Unbreakable:1,AttributeModifiers:[{AttributeName:"generic.movementSpeed",Name:"generic.movementSpeed",Amount:0.05,Operation:1,UUIDLeast:894654,UUIDMost:2872,Slot:"feet"}]}}}
# then the good news.
title @p tile {"text":"Buffed the boots!","color":"gray","italic":"true"}
title @p subtitle {"text":"Level 1 Buff","color":"red","italic":"true"}
# we target the boots and give a little puff of magic
execute @e[type=Item,c=1,tag=DropBoots] ~ ~ ~ particle reddust ~ ~ ~ 0.2 0.2 0.2 0 10
# let's see if we can play a sound too
execute @a[type=Player,x=-254,y=42,z=-63,r=8,c=1] ~ ~ ~ /playsound minecraft:entity.player.levelup master @a ~ ~ ~ 1 2 0
# clone the empty chest
clone -254 36 -64 -254 36 -64 -254 43 -62
# remove that tag
scoreboard players tag @a[tag=DropBoots] remove DropBoots
# get rid of that redstone block
setblock -252 40 -68 air
##
## So, we need a stack like this for every item, every buff level: Boots 1, Boots 2, etc etc.
