Divine Ward

 
Prerequisite(s): Ability to turn or rebuke undead
 
Benefit: Once every 24 hours, you can spend 10 minutes creating a magical ward between you and one willing target. For the rest of that 24 hour period, you can increase the range of a touch spell to close range if you target the warded creature. When you cast a spell in this manner, you expend a turn/rebuke attempt.
