Ring of Mind Shielding

While wearing this ring, you are immune to magic
that allows other creatures to read your thoughts,
determine whether you are lying, know your
alignment, or know your creature type. Creatures
can telepathically communicate with you only
if you allow it.
You can use an action to cause the ring to become
invisible until you use another action to make it
visible, until you remove the ring, or until you die.
