This whole "non-magic equals mundane" is what got us Caster Supremacy in the first place. The D&D idea that noncasters can't replicate or interact with magic stuff needs to die in a fire.
In D&D, magic is part of the world. It permeates the planes and interacts with people on a physical, mental, and spiritual level. A person without magic to a spellcaster is like someone without sight: limited, and does tasks the spellcaster does routinely with great difficulty (or not all). Through training, a blind person can make up for the loss of sight, but it would take lots of work and even then he can't discern details which require vision. Animals with poor eyesight use echolocation and can maneuver around their environment, but they still can't see. It is expected in fantasy fiction for magic to be more powerful and "beyond" the "Muggles."
"A Wizard Did It" is a very common excuse in fantasy games, used to justify all manner of stuff which we won't do with non-magic stuff. I propose a second thing to go alongside this:
"She's Just That Good."I've talked about in a thread on The Gaming Den about letting D&D characters replicate magical effects through skill. I once said that a smart character might be able to replicate divination spells through planning, investigation, and deductive reasoning.
Here's an example, from the shoot-em-up Anime Black Lagoon.Eda's (the nun with sunglasses) plan is pretty much guesswork and theory based upon the motivations of the runaway girl and the criminals, reinforced through some careful planning beforehand. She has no guarantee that the thugs will approach the girl and chase after her in such a way, but it happens according to plan. In a way, her recollection of events is similar to the Augury and Scry spells, and can be replicated this way in D&D.
"But wait, Libertad, couldn't PCs normally do this through
player skill?"
Yes, but it should be a special ability with game mechanics. Lots of times we play PCs who are smarter, wiser, and more well-spoken than we are. Additionally, making players think up of plans the normal way makes it reliant upon DM Fiat. Giving a Sherlock Holmes PC Divination-like abilities both reinforces the character concept, and gives the player a useful option when he can't think up a plan the old-fashioned way.
For more "physical" effects, there's Samurai Jack in the episode "Jump Good," where he trains among a civilization of sapient primates to
jump so high that he might as well be flying.The Barbarian claps his hands together to make a cone-shaped sonic attack because
he's just that strong.Samurai Jack can jump really high because
he's just that skilled at jumping.Eda the Nun can make assumptions about the actions of people who are not immediately present
because she's just that good at deductive reasoning."But this sounds like magic!" Right. That's exactly the point. Mimicking spell-like abilities is all fine and dandy, and we need this kind of stuff in D&D to encourage people to play noncasters, especially at high levels.
How did they breed an Owlbear? A Wizard Did It.
How does Sherlock Holmes know that the ground beneath him concealed a secret tunnel? He's Just That Good.
