Undead Horde 2: Necropolis

I had a little trouble getting this achievement. I could not figure out how to get to the Abandonded Crypt Mine. There's a quest called: To The Moon that requires you to go there. Idid not have a quest marker pointing me to the location, so I had to scour over previous locations to find it.

The quest To The Moon starts in Plunderer's Retreat. You want to head south to Sandstorm Valley, then Southwest to Bootrock Ridge.

In Bootrock Ridge, head south from the teleporter. Halfway between the green oasis and the next "main" northern path, the entrance to the Abandoned Crypt Mine will be on the north side of the path.

I used 3 Hierophants with the rest of my team with Mummies to clear the desert. If that wasn't working, I sitched to a team of bears to hit hard. Uprdages for Mummies and Hierophants are in the Corpse House.
