Perfect Sentinel

For the duration, you can keep watch over the emanation without sleep or distraction. You know when any Tiny or larger creature enters, exits, attacks, casts, breaks an object, opens a door, or speaks above a whisper, unless protected by Tier 8 or higher stealth or silence.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
