I'm looking for a spell which a spell caster would cast to permanently light a torch in their home. Or, maybe a hired arcanist would go around town at sundown to light the street lamps until the morning.
I'm certain I've seen an 'eternal flame' or similar spell around. Unfortunately, my Googling and Player's Handbook searching skills seem to be lacking today.
Is there any such spell, or do I need to look into homebrewing some permanent-enchantment rules?
