Cause Fear

Ranged spell
Daily
Target: 
One nearby enemy with 75 hp or fewer
Attack: 
Wisdom + Level vs. MD
Hit: 
The target is weakened until the end of its next turn. On its next turn, if it's unengaged, it does not attack and moves away from you. If it's engaged, the target attempts to disengage as its first action, and moves away if it succeeds. If it fails, it moves away as its second action (drawing opportunity attacks). In either case, it will not attack unless it has no options for escape.
Miss: 
The target hates you for having tried to scare it, and it wants to hurt you most of all, but it won't be any stupider than usual in pursuing that goal.
5th Level Spell: 
Target with 120 hp or fewer.
7th Level Spell: 
Target with 190 hp or fewer.
9th Level Spell: 
Target with 300 hp or fewer.
