Debating a number of things to post about, I think I'll keep this simple and straight-forward. I already mentioned these on my campaign blog, but it's useful to copy them over here.
Just a few ideas for cantrips, spells not meant to be especially powerful, but to add that bit of window dressing that makes playing a mage fun. These would all be legerdemain cantrips.
Creates an ordinary piece of household furniture, a chair, stool, small writing table, single-person bed or cot, cabinet, end table, cupboard or screen ... any of which will continue to exist so long as the mage is in physical contact with the item.
Thus, if the mage is sitting in the chair, laying on the bed, hiding behind the screen or inside a cupboard, the item will remain ... but upon letting go, the item will dissolve and disappear.
If the item receives a sharp blow, for example if it were used as a club, it would cause 1-3 damage upon a hit but then shatter and dissolve. If two persons were attempt to sleep in the single bed, the bed would last for an hour and then break up and dissolve. However, it will serve the mage all night and all day if he or she remains in it alone.
The DM may decide if a bench allowing two or three persons to sit is possible.
Creates any ordinary household object made of pottery or earthenware up to one cubic foot. Pots, jugs, cups, mugs, plates, vases or jars are possible, or things of that kind. The object will remain in existence until the sun rises the next day, until dropped (in which case it will automatically shatter and dissolve) or otherwise given a sharp blow. The object will serve as a missile, causing 1-2 damage upon hitting, whereupon it will break and cease existence.
If used gently, the object will serve to hold water, or as a chamberpot, and will even allow itself to be fired if its use is desired to melt metals in an oven.
Like pottery, only this creates an up to one cubic foot object made of wood, such as a smoking pipe, spoon, candleholder, whistle, toy, windvane, bowl, cup, birdcage, ball, box, etc. Like with pottery, the object can be thrown and will cause 1-2 damage, but will split and dissolve afterwards. The types of wood that can be created are limited to pine, spruce, fir, oak, chestnut and maple.
Creates a small, useful object for up to 1 hour, which can be used as normally. Such objects would include a corkscrew, woodplane, metal whistle, chisel, flint or steel (but not both), fish hook, sewing needle, dice cup or a die, a metal stamp (without an image) or tongs. Other objects may be agreed to by the DM, so long as it is nothing that can conceivably be used directly as a weapon or as a threat.
There, just a few ideas.
