I beated this level. it is hard, but possible. You need to rush forward with a lot of shredingers (i used 4) and theanos. best if you manage to teleport an enemy in a frontline at the start of the level. and send one theano and shredinger to the left. Then try to keep temp and rush as fast as possible. and the best if you manage to feed all shredingers. AND THEN PRAY TO ALL GODS OF SHREDINGERS TO TELEPORT THAT LAMIA INTO ONE OF YOUR VESSELS. but that is all.
