Key items to pop NMs in Abyssea.
I personally feel that a NM needing more than one KI to spawn it is a little overboard. Especially for NMs like Chloris where you need 4 items total. Especially since in this example you need it's item drops for Emp weapons.
Perhaps you could make it so that each of the items needed to spawn a NM will spawn it, but you only ever need one of them. In the example above... all 4 key items will spawn Chloris, but you only need one of them.
I just think this would make things less "annoying" since you are timed in Abyssea.
