Extend Senses (4e Ritual)
From D&D Wiki
You cast your senses foreward, peeking around the corner ahead of you.
|10 gp, plus a focus worth 5gp
|Arcana (No check)
This ritual creates a magic sensor in a square within 10 squares that you can see. You can see and hear as if you were standing there. You can make perception checks through the sensor. The ritual creates a scrying sensor—a shimmer in the air—that watchful creatures might notice. Creatures must succeed on a Perception check with a DC equal to 10 + your level to notice the sensor. They can’t disrupt or interact with the sensor in any way. Sufficiently powerful warding magic, such as the Forbiddance ritual, can block Extend Senses. If the location is warded in such a manner, you learn that as soon as you begin the ritual, so you can interrupt the ritual and not expend any components.
Focus: A mirror or a crystal ball worth at least 5 gp. The focus conveys what you see and hear.
