Celestial Cacophony
Prerequisites weapon innovation
Access Tian Xia origin
Your weapon contains a detonation chamber that launches fireworks, sparklers, and black powder pellets that sizzle, twist, and scatter on the ground in a cacophonous manner liable to annoy the entire Celestial Court. All creatures in a 15-foot cone extending from your innovation take scaling d4 fire,scaling d4 sonic damage with a fortitude save against your class DC; both the fire and sonic damage increase by 1d4 at 14th level and every 2 levels thereafter. The area affected by the cone becomes difficult terrain until the start of your next turn. Creatures moving through this area must succeed at a reflex save against your class DC or take 2d4 persistent fire damage.
Unstable Function You rattle your weapon violently to make it belch out even more pyrotechnics. Add the unstable trait to Celestial Cacophony. The area increases to a 30-foot cone, and all damage dice increase from d4s to d8s.
Traits
Effects with the fire trait deal fire damage, or either conjure or manipulate fire. Those that manipulate fire have no effect in an area without fire. Creatures with this trait consist primarily of fire or have a connection to magical fire.
This indicates abilities from the inventor class.
You must physically manipulate an item or make gestures to use an action with this trait. Creatures without a suitable appendage can't perform actions with this trait. Manipulate actions often trigger reactions.
An effect with the sonic trait functions only if it makes sound, meaning it has no effect in an area of silence or in a vacuum. This is different from an auditory spell, which is effective only if the target can hear it. A sonic effect might deal sonic damage.
A visual effect can affect only creatures that can see it. This applies only to visible parts of the effect, as determined by the GM.
