always having an illusion

[the_hulk]

effortless trickery says you can sustain a spell that has a duration of concentration as a swift action. can you then have a silent image always?
i played my guy as always appearing in deep thought,taking up the concentration.

Could you give a reference for "effortless trickery"?

Effortless Trickery
Your natural knack for illusion allows you to maintain at least one illusion spell with little effort.

Prerequisite: Gnome.

Benefit: You can maintain concentration on one spell of the illusion school as a swift action. This has no effect on spells of other schools or on illusion spells with durations that don’t depend on your active concentration. While you may only maintain one spell as a swift action, you may take your move and standard actions to maintain other spells normally, if you wish.

Normal: Concentrating to maintain a spell is a standard action that does not provoke attacks of opportunity.

found in gnomes of golarion

It sounds like as long as you can take a swift action to maintain concentration, the illusion will last until you stop taking swift actions to concentrate (i.e. sleep or use a swift action for something else) or something ends your concentration (i.e. taking damage and failing a Concentration check) or the spell (i.e. dispel magic)
