        end
        return TRUE
end

Can it be to summon Dragon Hatchling, Dragon Lord Hatchling and Frost Dragon Hatchling randomly? And btw, when i use it, it always says "cannot summon creature while you are in a protection zone" and i don't know why. And one last thing, is that monster going to attack with ur like a summon, or i can be like that?

Thanks beforehand!
