Permanence is intended to function ONLY for Ignis Fatuus and Fata Morgana, not for higher levels of Chimerstry. This is the case for the tabletop books (Vampire the Masquerade (Revised), p. 154; V20, p. 145), but was omitted from the LARP books. We are treating this as an oversight and Permanence will function only for illusions created with the first two Basic levels of Chimerstry.
