A Sound Of Thunder
Chime of Awakening
This silver chime sounds an alarm in the minds of you and your resting allies
You set the chime of awakening to ring when a specific trigger occurs within 10 squares of it. Example triggers include the presence of anyone other than you and your allies, the light of the sun touching the area, or the appearance of a specific character or type of creature. The chime rings in the minds of you and all allies within 10 squares of it. You and affected allies are instantly awoken (if asleep) and alert. The chime of awakening can be fooled by creatures in disguise. It makes active Perception checks with a +10 modifier.
