It's not "main spine". The main spine campaign at this level is Glumdoll.

Yay, NEW gear L20-25. I sure hope there is a helm. I mean a pink one. There really aren't enough mage items in these levels, either. But one thing for certain, there will be pick-axes... there already are, but I bet there will be some better ones. Also, what about all the gem swords we get in Glumdoll and under the Sarcophagus? I bet there will be pink versions of each gem blade. Now that will be something worth collecting!
