Green AOE Ring

[The Crucial One]

I'm not much of a coder and was hoping someone could point me in the right direction as I am looking for a way to use the Green AOE ring that u get from casting spells like Ranger spell: Storm of Arrows. Reason behind this is I'm working on interactive Solo Battle Scenarios and would like to be able to place objects/NPCs without the need of them having to run around and have the Objects/NPCs spawning on player XYZ coordinates. Any and all help would be much appreciated,

Thanks Again,
Crucial One
