If the target fails his save, it refrains from attacking or targeting the caster for the remainder of the round. This spell can be cast during the target's turn, after the target announces its intention to target the caster. If the target was attacking and becomes subject to the spell it can pick a new target, but it takes a -4 circumstance penalty on the attack roll. If it was casting a spell, it can redirect the spell, but must succeed on a Concentration check (DC 15+Lv) or the spell is wasted.
