@Draco18s I understand. Have a good day, and thank you for giving the time to help me!
I'll just post the working code here just to help any future users that happend to stumble across this thread:
@Override
public void addInformation(ItemStack stack, World worldIn, List<ITextComponent> tooltip, ITooltipFlag flagIn)
{
super.addInformation(stack, worldIn, tooltip, flagIn);
tooltip.add(ITextComponent.func_241827_a_("'Lore'em Ipsum! Ha!"));
}
