Forum:Relinquished Clarification

1.Can Relinquisheds' effect use monsters that are face-down? the card text doesn't specify

2. If I have Relinquished and have an opponents monster equipped to him with Ritual cage active on my field does my opponent still take the battle damage since it is considered effect damage while I take no Battle damage due to ritual cages effect?

3. If Relinquished is equipped with a monster can I destroy that monster by taking another of my opponents monsters, since he can only be equipped with one at a time?

Please answer with concrete information and examples if you can
