Velleity

Velleity is the weakest spell a mortal creature can cast. It is primarily used as a litmus test for magical ability; anyone who cannot cast it has no innate potential as a spellcaster, and is incapable of developing such. Hence, it is available to all arcane spellcasters of any class who attempt to cast it, without counting as a cantrip of their class(es). By simply speaking aloud, and concentrating on your arcane focus, you create a minor ripple in the very foundations of reality.

The mechanical use of this spell is to apparently duplicate any other non-enchantment cantrip with a casting time of one action or longer. However, the cantrip is not actually duplicated; rather, everyone within 30 feet of the caster sees a obvious, ghostly illusion approximating the results of the duplicated cantrip, lasting about a round, but with no other actual effects.
