Ignite Fire

Regular 
Produces a single spot of heat, and is used to set fire to a readily flammable object. It works best on paper and cloth, and will not affect any item that would not burn in an ordinary fire. In particular, it will not set fire to a living being! 
Once ignited, the fire burns normally.

Duration: One second. 
Cost: Depends on the amount of heat desired:

• 1 – As though a match had been held to the subject. Lights a candle, pipe, or tinder in one second.
• 2 – As though a torch had been held to the subject. Ignites paper or loose cloth in one second, ordinary clothes being worn in four seconds.
• 3 – As though a blowtorch had been held to the subject. Ignites dry firewood or clothes being worn in one second, leather in two seconds, and heavy wood in six seconds.
• 4 – As though burning magnesium or phosphorus had been held to the subject. Ignites coal in one second, heavy wood in two seconds.
