@GiskI'm thinking of using some minor magic, a cantrip called Cocoon, to create an unseen umbrella-like shell anchored over my witch as she goes for coffee. Is that okay?
Now that I think about it, what would be some other cantrips that mages might use?
Blade - turns a fingernail into a small, sharp cutting surface. Great for opening boxes or letters, can inflict a paper cut.
Chill - cools something that your hand is touching, like a drink or a burn.
Cocoon - creates a light protective field around someone and whatever small items they're carrying. Acts like an invisible umbrella to keep out rain or an invisible sleeping bag to keep warmth in. Cannot block attacks.
Flutter - used to direct the flight of something light, like a feather or a piece of paper, through the air or along the ground. Some have been known to prank with this by dragging dollar bills along the ground.
Fly - allows the caster to fly with the aid of a broom or mop. It's important to remember you're not to ride the broom directly, but to levitate yourself above the broom slightly to avoid discomfort. Or install a bicycle seat and handlebars, and/or footrests. Alternately, one can hold unto a parasol or umbrella. Please remember to keep a firm grip on your broom or umbrella at all times.
Forget Me Not - the ability to imbue an object with a thought, useful for remembering combinations, phone numbers, or other small details.
Ignite - with a snap of the fingers, it creates a small flame dancing on the tip of a finger (like the index), suitable for lighting a candle, laid logs and kindling in the fireplace or campfire, tobacco pipe, cigar, or cigarette.
Ignore - Projects a "somebody else's problem" field around someone so that they are left alone. People know
something is there, but unless they go looking through the corner of their eyes, their eyes just slide off it. Can be defeated by the All-Seeing Eye spell.
Light - used to create a small floating ball of light. This may be anchored to a wand or staff, or to the wall.
Magic Eye - allows you to spy from a spot on flat surface, like a window or walll.
Mend - able to fix small tears or cuts in fabric, cracks in wood or stone.
Out Out Damned Spot - used to remove small stains.
Probe - an invisible spot of force projected three feet in front of one's fingers, allowing them to touch something without actually using their hands.
Puff - creates a sudden puff of white smoke.
Stirrer - uses a finger to direct an object like a spoon or a ladle to stir something, either a cup or a cauldron.
Warm warms something your hand is touching, like a cold cup of coffee or tea, a slice of pizza, cold butter, or a sore muscle.
Whisper - a way of throwing your voice to someone in your line of sight, but that nobody else can hear.
Fly might be too much as a cantrip.
