Ok Im no pro but I found this out and it works for me.
1: Use somthing like navcat
2: open in my Db cq_generator
3: Look for colum row npctype
For this example I will use Madbulls in cronus also easy to test.
Mob Ids:
1000 = Normal Madbulls
1001 = Madbulls Lv12 (maybe Boss)
1002 = Madbulls Lv13 (maybe Boss)
1003 = Madbulls Lv14 (maybe Boss)
4: Right Click colum npctype bar sort by ascending
5: Look in npctype colum for 1000 (in total there should be about 22)
6: Leave the first 7 (1000) they are normal mobs
7: Next 5 change to 1001
8: Do this 2 more times useing 1002 / 1003
9: Only change the 1000 not any other
Then Start server and go to Cronus and look around the start area
P.s colum max_per_gen = the amount to be respawned
Rest_sec = amount of time between respawns
Im sorry if this is not to clear but its my first time doing this
Thanks go to all who helped me and to cookiec1025 for the serverbackup.zip
and for putting me on the right path to this
