I managed to get my Restless Shadeling the other day - these are the only ones you can get from Deadwind Pass so if you're chasing the achievement for each zone you need to get there at midnight to grab one. They're level 16-17 Undead so make sure you're prepared! Right on the dot at midnight they pop up underground (The Master's Cellar) and there are tons, so make sure you get down there just before midnight so you can beat the crowds. I have a green quality one but I am searching for that rare :)
However, Minfernal, Sand Kitten, Giraffe calf and Spawn of Onyxia continue to elude me. I wonder where they all are! I have read that the spawns are like the fishing pools - if you clear out the other ones, you'll get them spawning again. I was trying to do that, but I saw people camping the areas and thought, well I'm not clearing it out for them to get my spawns! So I stopped.
I don't really like Undead pets. The invulnerability when the rez after death is kinda cool but lasts one round but they make up for that with weak damage overall. I like my mechanicals.
And I can't believe that Spawn of Onyxia is the ONLY dragonkin you can catch, no wonder everyone is trying to get it! There are a few humanoid ones and magic ones so hopefully I can nab one of those for the achievement. But that little dragonkin... ugh.
Ok, time for bed. My cold has made me medicate myself which has made me semi comatose whilst trying to quest.
