We all knew it was coming and just in time for All Hollow's Eve. Spooky Mount Packs are available in the Cash Shop. I suppose a Necro could use them year round. From what I gather they are also craftable but not confirmed at this point. There's also a Halloween Sale going on so the packs are only 1600 Gems instead of 2000. Be sure to pick up the free fireworks in the store while you're there. It's said the final rocket gives a 50% Magic Find Boost to nearby allies.
I can hardly wait to see what they have for Christmas.
