More than an issue, it's a suggestion. When someone change on the configs, for example.
On Coal Armor
# Enable/Disable The Coal Boots NightVision [default: true]
B:enableCoalBNightVision=false
So here my idea, to make it only show that if the config is true and also, in the case we have
# Enable/Disable The Full Coal Armor Effect [default: false]
B:enableFullCoalArmorEffect=true
PS: What I'm not sure how would it be handled, when you have 1 piece giving the effect, and also the full set set to true, I guess that wont make sense as you would have full set, but you already getting the effect for the 1 piece left on true on the configs ;)
