Basically he is saying that if you type /w GMCode TriggerEvent 25 on Zone10, the bless will activate.
If you can somehow recreate that instance on other zones like Zone20 and Zone25 on which /TriggerEvent 25 will activate when you kill a player, then you would have successfully added the perfect bless event on Anaka and Vedi Kruma. Assuming you already set /TriggerEvent 25 on Zones 20 and 25 to trigger the task required for the bless.
I know how it all works, I just don't know how to make the Zone Trigger the event like Zone 10. I think it's hard coded on the Zone anyway, it's not really my priority but once I figure it out I'll gladly share it here.
