While wearing this helm, you can use an action to cast the Detect Thoughts
spell (save DC 13) from it. As long as you maintain Concentration
on the spell, you can use a Bonus Action
to send a Telepathic Message
to a creature you are focused on. It can reply — using a Bonus Action
to do so — while your focus on it continues.
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 used, the Suggestion
property can't be used again until the next dawn.
