it appears the spawn for the sarnak hatchlings is extremely low. lots of gobbys and lots of tigers lots of skellies but so far in 2 hours of hunting them and clearing every mob i could see in the noob area i found 2 hatchlings. They are used for the necromancer skull cap quests but for a noob quest requireing you to have 8 brains...i think a few more need to be spawning. They are warring factions with gobbys but there are way to many gobbys spawning imo.
