Changing spawn rates of rare mobs

[veramon]

Hi there, and I am sorry if this has been answered already, but I could not find a reply that could help me when searching.

So, I have a fresh install of Akkadius server running on linux. Everything works very fine, but I am interested in changing the spawn rate of all named/rare mobs. Lets use Amb. Dvinn in crushbone as an example.

I would like him to spawn much more often than he already does. This is easy to fix in mysql, but the issue comes when I want to do this for -all- rare/named npc. There are just so many of them, and going at it searching one by one will take ages.

Is there a way to find all named/rare mobs in the database? I haven't found any table in the database that identifies the npcs as rare/named.
