well i think it was more of the mobs were in the db already but you used the item in the zone and it would spawn the mob at your spot so that when you left the zone it stayed. i figured if they could do this on guildwars back in 030 days it should be cake walk now :p
i might have to set up some spawn conditions instead...kill mob x amount of times and new mob spawns in its place
if anyone comes up with something on this....please let me know
thanks jordan and trev
