|Type||sonic energy cannon|
Knell cannons are an advanced version of ancient Auhtai cannons. Both types use a sonic energy technology called Päiki-Synhö. The knell cannon is a shorter range weapon that produces a devastating sound wave. They require no ammunition, but are limited to the number of times they can fire each day. A knell cannon can fire five times with safety, each successive fire in the same day has a 10% cumulative chance of shattering the bell and destroying the weapon. The weapon has a 30' conical blast that deals 10d6 sonic damage (Reflex DC22 half).
