You only will need 2 effects one persist and one damage effect.
Create the persist, have it create a periodic effect using the damage effect, use the period count for the amount of shots and the period interval for how fast you want them to shoot. Use initial delay for the delayed effect. Create some period offset coordinates, the more you put in the more random you will have - and flag the persist for "Random Offset".
For the damage effect, just create it and set value for combat for the damage per shot, and for the AOE use the search on the damage effect, there you can set a radius for the AOE.
