Smokepowder Surface

Smokepowder Surface is a type of Surface created by throwing or breaking a Smokepowder Barrel.

Igniting a Smokepowder Barrel with  Fire damage creates and detonates a Smokepowder Surface (while also dealing a large amount of upfront  Force damage), whereas breaking the barrel without igniting it only creates the surface.

Properties

Stepping inside a Smokepowder Surface has no effect.

However, when ignited, a Smokepowder Surface has the following effects for all creatures standing on it:

• 2d6 (2~12)  Fire
  damage ( DEX Save, DC 12, to halve)
• 2d6 (2~12)  Force
  damage
• Creatures caught in the blast are knocked back
• The Smokepowder Surface becomes a Fire Surface (which immediately inflicts the Burning condition)
