Your magic and imagination are so powerful and intense that you can create reality by sheer force of will.

Whenever you cast an illusion spell or the minor illusion cantrip, roll a D6. On a 6, an aspect of your created illusion becomes reality. The DM decides on how much of your illusion becomes real. If the created illusion is a living creature, it stays for the duration of the spell with a minimum of one minute and afterwards vanishes into thin air. Objects created in this way are mundane and not magical, but give of a faint aura of illusory magic.
