Helm of telepathy

While wearing this helm, you can use an action to cast the detect thoughts spell (save DC 13) from it. If
you maintain concentration on the spell, you can
use a bonus action to send a telepathic message to a creature you are focused on.
While focusing on a creature with detect thoughts, you can use an action to cast the suggestion spell
(save DC 13) from the helm on that creature,
once per day.
