Pretty standard mage/structure build. Archangel armor lets your shields scale over time (assuming you don't get flamed to death like I did on floor 16). Wizard cap + ancient tome + wizard's robe gives you 8 mana regen a turn. Gemstone heart + cleansing rag to help stay alive vs. poison and damage that overwhelms your shields on the first turn before scaling kicks in. Ring of doom to scale the wand damage, I had fun trying to figure out the optimal amount of buffing to do with the ring of doom (think it ended up being 11 times on turn 1). Poison snake + flame enemy was ultimately the builds undoing, as the flames scale out of control and poison is unblockable. Got to floor 16 though so still pretty happy with the build.
The update definitely made the game much harder. Haven't tried archer/cleaver builds yet since it dropped, this build was just what I ended up getting up and running today.
