The first time I was camping for Demidos, I was sitting there with a gnome warlock next to me waiting for him to spawn around 1 am. I decided to make convo with the gnome lock while we waited, and he told me he had been waiting several hours, but hadn't seen it yet, and that he was watching family guy while he waited.
Eventually one hour passed and I think he got tired of me talking with him lol, so he decided to head out for the night, and literally not 2 minutes after he left. It popped! I was so shocked when it popped my adrenaline went into over drive. Since this was literally a few days after WoD release, I didn't know much about this mob or pet. I just knew I wanted it.
As soon as it popped I PMed my brother who was also on and is also a pet collector, but he is more of a PVPer.
I told him this mob was up and that he should come help me with it if he wants the pet. He asked me a bit about it, and then when he realized I was talking about the Demidos boss he replied with "Holy, that thing takes a group".
But I insisted that two of us could handle it at 100, I was a mage and he was a warrior.
So he came to me right away and we blew all our cool downs to try and take him down. It felt like an epic battle as we were both probably below 630 ilvl lol, I was barely 610 at the time. We were around 3-15 percent health the whole fight, so it felt crazy that we were staying up as long as we did! We used all sorts of cds and self healing lol.
When the mob hit around 30 percent life, a few random players came and helped to finish it off.
My brother and I both got the pet on our first kill! At the time this pet was going for 30-40k, but my bro said he wasn't going to sell it. It was a pretty cool kill and drop for both of us. Because of that sort of lucky late night kill, it's def a sentimental pet to me.
