The spell created a banner of any desired size or shape to appear where the caster wished. The banner could even glow, illuminating the surrounding area similar to a light spell. The banner was accompanied by loud fanfare. The fanfare only lasted for a minute, but could be dismissed whenever the caster desired.
This spell could be used to trick others into believing they were encountering a ghost or other watchful guardian. By far the most popular use of this spell was as a rallying call on the battlefield.
In addition to verbal and somatic components, this spell required a real trumpet to cast. Acceptable substitutions for a trumpet included other horns or smaller models made from other materials.
