Trickery

You think of something, and will it to happen, and it does. When you cast Trickery, create anything anywhere. The thing created can be physical, or an illusion. It can be a sound, an object, a creature, anything. The thing created cannot occupy a space something else is in already, though it can occupy the space directly around it. The created thing, if it is an object, can exist for as long as the caster is alive if it is no larger than a 1 foot cube, up to 6 years if it is no larger than 3 foot cube, up to 2 years if it is no larger than a 6 foot cube, up to 10 months if it is no larger than a 10 foot cube, up to 4 months if it is no larger than a 20 foot cubeb, up to 1 month if it is no larger than a 50 foot cube, up to 2 weeks if it is no larger than a 250 foot cube, up to 10 days if it is no larger than a 500 foot cube, up to 3 days if it is no larger than 2,000 foot cube, up to 24 hours if it is no larger than a 5,000 foot cube, up to 6 hours if it is no larger than a 12,000 foot cube, up to 2 hours if it is no larger than a 25,000 foot cube, up to 30 minutes if it is no larger than a  60,000 foot cube, up to 2 minutes if it is no larger than a 100,000 foot cube, up to 30 seconds if it is no larger than a 300,000 foot cube, and for all effects larger greater than a 300,000 foot cube, the effect may last no longer than 10 seconds. The same times applies to sensations such as sounds, provided the range is the distance at which they are perceived. You may not have more than 3 effects created by this spell active at once.

This is a spell of immense potential, that exhausts those that cast it. 10 minutes after casting, whoever casted it gains a level of exhaustion, and cannot cast this spell again for until their next short rest.
