A warm, bright fire quickly erupts from a single spark struck off this magical shard.
Wondrous Item 520 gp
Utility Power (Illusion) Daily (Standard Action)
Effect: You light a campfire using this flint that burns without smoke or sound. The bright light of this magic campfire is invisible from outside its 10-square radius, though creatures and objects within that radius can be seen normally with darkvision or if existing light allows. The campfire is a normal fire in all other respects. The fire lasts for 12 hours (requiring no additional fuel) or until it is extinguished normally. The flint can be used to light lanterns and other fires as normal, but such fires gain no magical qualities.
