Pyzjin, Quillmane and other rare spawns

[litlamzetiv]

On my server, I'm removing (or greatly reducing) the number of PH's that spawn for rare spawns. I'm doing this by using the NPC EDITOR and modifying the spawn groups to remove (or reduce) the available PH's. This worked great for guk, but I came into a problem with SolA & SolB. Specifically, I couldn't find spawn groups for the following:

Lava Elemental, Captain Bipnupple, Singe, Kobold Predator, Goblin Bartender, Goblin Torturer (some of these didn't even seem to have spawn entries). Likewise, I found an entry for the Death Beetle in SolB, but didn't find a spawn group. Does this mean he doesn't spawn at all? What about mobs like Quillmane, Pyzjin, etc.? Since they don't have spawn groups, do they not spawn?

Or is there some other way to spawn mobs that I'm just not aware of? Since Lord Nagafen also doesn't have a spawn group in the database, but I've seen him up, there has to be another way to spawn such critters. Can someone please help me understand what I'm missing?

Thanks,
