Is it possible to remove/apply damage to item yet? By this I mean: you have a sword and the lore is "+5 Attack Damage". Does anyone know how I can remove this or even change it? Thank you in advanced.
Armor Color: Lore can't be removed without the armor losing its color for the client FireWork Star and Firework Colors: Lore can't be removed without the items losing their color for the client Potions: The When Applied: thing is removed if you use custom potion effects (nbt tag rather than dmg value) afaik and the Poison: 3:00 can't be removed without making every potion look like a water bottle for the client. Enchanted Books: Very possible, but makes no sense because the user needs to know what the enchantment is. Music Discs: As stated before: impossible, is client side. So your best bet is to use AttributeHider combined with custom potions with nbt tags rather than damage values. Not too sure what you are trying to do.
