I was able to do it in precisely 15 turns, IIRC. My deck is Ishtar(V)+2, Vassago(C)+2, Reginliev +2, Bennu(V) +2, and Ywain+2.

When you get to the boss, burst him all the way down to his resist state by Pound > Rend > Slice > Upper > Dice x 7 > Smash. With your assists, you should get his first resist, which he'll then subsequently heal. Kill the lizardmen, and go back to beating his face in until he dies, or beat his face in and then kill the lizardmen. Your choice there, depends on how many pots you have, and if you have a defense passive to soak blows better. Note that in order to do this, you must spend as few turns as possible clearing earlier levels. Most previous waves should only take one turn, with the exception of some which require two or three, but overall, the 6 waves leading up should only consume at most 9 turns for a healthy amount of turns to work with.

Well, that's what worked for me.
