Heaven's trumpet

Heaven's trumpet was an evocation spell that sounded music that could paralyze a celestial archon's enemies.

Users
This spell could be cast only by archons who were bards, clerics, or emissaries of Barachiel.

Effect
The caster emitted a blast of music of such perfect beauty and clarity it struck those who heard with awe. Enemies up to 120 feet (36 meters) who not withstand it could be paralyzed for up to 24 seconds.

Components
It required a somatic component, the caster's own archon nature, and a focus in the form of a well-made trumpet, which was blown during casting.
