This is dried and powdered dragon blood. After 2 rounds of exposure to air (end of the second round), it will ignite. A handful can be case to cover a 3m square area in front of the thrower. It will burn for a round, doing 40 points of damage to all those in range.
This blue glass bottle can hold up to 10 handfuls of dragon dust. When it seals, the seal is air tight. It can be used to blow dragon dust uniformly so as to cover a 10m square area. It will prevent the dust it is containing from catching on fire as well, unless broken. If broken, all things within 5m radius take the full effect of the stored fire, those with 10m take half – tumble for half damage.
