First wave: pick up 6 chests and build auras and beams. Switch to adept with mana collection (genie, dice, etc.), pre-place lt (slightly closer to str drain) and dst (slightly farther from str drain). Pull in initiate boost split, start wave, start initiate boosting, then gather mana on adept to build 5lt and 10dst. You should have 8du remaining; this is intentional.
Second wave: Switch to tower booster and pull in a summoner (or anyone with hover) split. Start wave, begin both boosts, then fly the summoner out to grab santa's book. Immediately leave with this split once completed.
Third wave onward: Double boost. If you feel like it, upgrade all your towers, but only the buff beam needs to be maxed. Grab santa's toys in between waves.
Final wave: Run barb, tboost, dps monk (ab2 spec), and range/rate guardian summ. Stand summ on the str drain. Stand dps monk at center core. Build damage totem at hint 2) and upgrade to max.
Boss wave: Run around killing bosses with battle leap, pound, and hawk + lightning stance. Use tornado stance to get around faster. You have two monks, one on upper and one on lower, so utilize their hero boosts when they are in the vicinity.
