The API of EliteArmor is very extensive and it allows you to create your own effects very easily

• View API Class

How to create your own effect

Create your own class for your effect and make it extends Effect

Then edit the name, description and usage and make sure you remove variables from the class method and only leave the plugin variable

public class Test extends Effect{
    public Test(Plugin plugin) {
        super(plugin, "TEST", "This is a test", "TEST:[VALUE]");
    }

    @Override
    public void init() {
        registerEvent(BlockBreakEvent.class, event -> {
            Player player = event.getPlayer();

            if (!hasEffect(player, getName())) return;

            for (String[] argument : getArguments(player, getName())) {
                String value = argument[1];

                Bukkit.broadcastMessage(value);
            }
        });
    }
}

Create your effect in the class and once you are finished add this to your onEnable but make sure EliteArmor is a dependency and is loaded

EliteArmorAPI.getArmorAPI().loadEffects(Test.class);
