Cause Fear
Cleric Attack 1
Ranged 10
Target: One creature
Attack: Wisdom vs. will
Hit: The target is compelled to take a free action to move as far away from you as it can, moving a number of squares equal to its speed + your Charisma modifier. It avoids hindering terrain and difficult terrain if it can. This movement is not considered forced movement, so it provokes opportunity attacks. [PH:63]
