This is yet another map that's actually quite intimidating when you first take it on, but becomes rather straightforward with the right build. In particular the constant stream of Anurian Erudites in waves 3 and 4 seems overwhelming at first, but two fully upgraded Shadow Archers plus stalling with reinforcements takes care of the issue. As for the rest, Spectral Mausoleums with Possession spam wins the day as usual.
A key to note on this map for any mode is the importance of the build spot at the very top of the map near the north entrance. It can attack both the north entrance lane as well as the west exit lane, and gargoyles on a Spectral Mausoleum can swing back and forth between the two as needed.
