This is a build for WW2 on Ascension difficulty in Redux. Once all auras and beams are placed first at the start,do the following:
1: Place snowball tower facing towards the barrier west of top core. This will help to deal with the ogres what will be aggroed toward the DST/LT stack here
2: Place 1 LT and 4 DSTs in a stack,with one DST each facing all four directions as shown on top right
3: Place 3 Fireball towers and one LT on the buff beam,with the fireball towers angled as shown in top right
4: Build 1 SAM turret facing the core at bottom left
5: When you have enough mana,place Spider Queens where the tags with the number '5' are
Make sure to fully upgrade everything once all minions and defenses are built,and you should be able to handle all the bosses. I have not tested this for survival or ruthless.
