Aefirth's Hearth Fire Ritual

This spell can only be cast  as a ritual, which takes 1 hour to complete  and  involves  the wizard burning 500  gp worth of ruby dust  in a brass brazier  at  dawn after a full moon.  Upon casting of this ritual and for the next minute, a soft blue heatless  flame wreathes the wizard's  hand.  During  that time  the wizard can touch any ready fuel source and enchant  it.  The fuel source will instantly light as though struck by normal means.  The target can be anything that would  normally be set alight  to burn (i.e. candles, fireplaces, campfires, torches, lanterns, braziers) and has a ready fuel source.  The flame sheds light and heat as a normal flame of its size, but does not consume the fuel  upon which it is cast.  The flame otherwise  acts as a normal flame, producing heat and consuming oxygen.  Since the flame provides heat and will burn objects placed in it,  the flame cannot be covered.  The flame can be smothered or extinguished like a normal  fire, and if someone smothers the flame it will go out  normally.  The flame will burn eternally or until the fuel source is destroyed, the flame is smothered or otherwise  extinguished.

As a bonus action the wizard  who enchanted  the source can douse or reignite the flame.  If the  flame  is  not  lit  by the  caster  again within 1 year, the enchantment is lost.
