Brawler: Blow everything. Save DFD for the mirages as you need to get that 250*5 potency DFD.

Blaster: Elusive Jump for Rockets. Save SSD/DFD in case more rockets. Blow them both at sub 10% to force him to skip a mechanic, as you don't need them anymore.

Swindler: Save SSD, do not use in opener. If you're planning to manually AOE burn the adds, then the SSD would serve as a brilliant cap closer here. Elusive Jump gets bugged I've noticed because of the floors. I don't know why.

Vortexer: Same stuff here. Save all Jumps. Use SSD if you get the first compressed water or hailstorms. Use DFD/Elusive for second. SSD should be back up for the Ultra-Flash. Repeat like that.
