The chronomancer selects a spell of 4th Level or lower that ze can cast, that has a Casting Time of 1 Minute or less, and that can target only a single creature.   Ze casts that spell, called the Permanent Spell, as part of casting Permanency, expending Spell Slots for both, but the Permanent Spell comes into effect with an infinite duration, and no longer requires Concentration from the chronomancer. The maximum total level of spells that can be made permanent cannot exceed the chronomancer's proficiency bonus.   For example, a Permanency Spell cast See Invisibility allows the chronomancer to see invisible creatures and objects as if they were visible until ze chooses to dispel this effect.   While standing within a Field of Anti-Magic or a Similar Effect, the effects brought on by a Permanency Spell are suppressed, these effects cease to be suppressed as soon ze exits it.
