I really dislike false modernisms in my fantasy. If you want street lamps and cell phones, please, by all means, use a modern setting. Urban fantasy is great in allowing you to do magic and swords while having all conveniances of modern civilization. If you can't think without smartphones, then don't. Fuck speaking stones. Fuck eternal lights. Let me state it here:
ANY SUFFICIENTLY MUNDANE MAGIC IS INDISTINGUISHABLE FROM TECHNOLOGY.
There, I said it. If every other dude can cast light/bread/whatever, there is no medieval society. Nope.
So magic better be rare, hard, opaque, weird, dangerous. Have the supernatural as a hint, not an everyday thing. And don't forget: If you can actually feel your god's power via visible and undeniable miracles they work through your or someone else's hands – please don't call it fucking faith.
