Battlecry!'s Shock and Awe seems fairly good for a 5th-level arcane and occult spell.

>Shock and Awe [three actions], Spell 5

>Auditory, Concentrate, Emotion, Fear, Illusion, Manipulate, Mental, Visual

>Traditions arcane, occult

>Range 100 feet; Area 50-foot burst

>Defense Will; Duration 1 round

>You create the illusion of cannons exploding, bullets and arrows flying, and magical ballistics firing, as an overwhelming torrent of information, both visual and auditory. Enemies in the area must attempt a Will save.

>Critical Success The enemy is unaffected.

>Success The target is frightened 1.

>Failure The enemy is frightened 2 and stunned 1.

>Critical Failure The enemy is frightened 3 and stunned 2.

On one hand, this can definitely run into immunities. Three actions is inconvenient. The duration is only 1 round, making the debuffs short-lived. On the other hand, those are good debuffs (e.g. stunned alone locks out reactions), and the range and ally-friendly area are fantastic.

What do you think of this spell? Is it on par with Synesthesia? Does the duration limit it too much?
