Quick question about the staff of tzeentch on the lord of change. If bring a unit of spawn and they die, then i kill a model in close combat with my LoC can I use it to create more spawn or do I have set aditional points aside to bring more spawn into play?

As per the latest faqs, you have to set aside reinforcment points for any spawn generated this way.
The rule doesn't allow for you to add to existing units.
