Benefits
You can, as a standard action, use one of your uses of Channel Positive Energy to cause all undead within 30 feet of you to flee, as if panicked.
Undead receive a Will save to negate the effect.
The DC for this Will save is equal to 10 + 1/2 your cleric level + your Charisma modifier.
Undead that fail their save flee for 1 minute (equal to 10 combat rounds of 6 seconds each). Intelligent undead receive a new saving throw each round to end the effect.
If you use channel energy in this way, it has no other effect (it does not heal or harm nearby creatures).
