|This spell produces a noise emanating from a place of the caster's own choosing.|
Projected Noise was a level 2 Hexes spell which created a deafening noise originating from a tile of your choosing, anywhere on the known map of the current level. Long thought to be useless, this spell was capable of trivializing later Ziggurat floors. One needed only to cast it at the lowest point of the Ziggurat and run around the upper part to avoid all monsters and gain access to the loot/stairs.
Projected Noise was removed from Crawl in 0.11.
