Kiri's Guardian Sigil
(Evocation)

Range:  0
Components:  V, S
Duration:  Special
Casting Time:  1 round
Area of Effect:  One object touched or 10 square feet per level
Saving Throw:  None

This spell is in many ways similar to sepia snake sigil in the Unearthed Arcana in that it traps people in a shimmering field of force. The spell can be cast upon an item or upon an area of up to 10 square feet per level. When casting the spell, the caster must specify the conditions that will set the spell off. Examples of possible conditions are for example: "anyone who touches my spell books besides me", or "anyone who walks on my welcome mat without first saying arador".
One person per level can be named in the casting of the spell. When the spell is discharged, the target is trapped in suspended animation inside a impenetrable field of force. There is no saving throw against this spell. The only way to remove the field is to dispel it (against the caster's level), or wish it away.
