It worked for me on 5-6k stats, dragon just died from DSs under monk boost. Though auras on the plane don't reach the second stairs from central crystal (check the screenshot below, they are indicated with red arrows), so I moved auras towards the stairs (dark red arrow on screenshot). My monk has 5k range, while my EV has 3k range. Maybe with ini remote boost they could reach, but I didn't test.

I lost around 4 times because dragon destroyed all my tower once he threw fireballs because there were 2 non trivial issues made by me:
1) Don't put any character on a tower, fireballs will explode against him destroying towers.
2) Put the second layer of reflection beams to the first one as close as possible with no gaps.
