Scry Trap

Abjuration
Level: Cleric 5, sorcerer/wizard 5
Components: V, S, M
Casting Time: 1 standard action
Range: Touch
Target: Creature touched
Duration: 1 hour/level
Saving Throw: See text
Spell Resistance: See text
You ward a creature against scrying, granting it defenses capable of terribly wounding any would-be scryer. If the subject of this spell comes within 10 feet of a sensor created by a divination (scrying) spell, the scry trap automatically activates. The caster of the scrying spell takes 1d6 points of damage per your caster level (maximum 15d6) and is blinded for 1 minute. A successful Will save halves the damage and negates the blindness; spell resistance also applies against this effect.
In addition, the caster of the scrying spell must succeed on a caster level check (DC 10 + your caster level) or the scrying spell is dispelled immediately (spell resistance does not apply against this effect). The subject of scry trap becomes automatically aware when the spell triggers, although the subject gains no knowledge as to the nature of the scrying spell or its caster.
Special: A character with any Mark of Detection dragonmark, or with the Favored in House feat (Medani), casts this spell at +1 caster level.
Material Component: Powdered glass from a broken mirror.
