Mass Hold Person and Line of Effect

[JDawg229]

So a player in my game tonight cast Emergency Force Sphere in response to an enemy casting Mass Hold Person. One player argued that because the caster can still see the target, he can still target him. The other side was that Emergency Force Sphere would block Line of Effect, meaning they wouldn't be targetable, even though there is Line of Sight.

Which spells use Line of Effect, which spells do not?

You must have a clear line of effect to any target that you cast a spell on or to any space in which you wish to create an effect.

Any spell that targets another or that creates an effect requires a clear line of effect.

Line of Effect is still needed.
