I also recommend using exp 118. Getting rid of at least one enemy in the boss node really helps when you're facing the lottery of the Night Battle. Sparkle your support fleet as well as your main fleet - it brings out their true potential. Trial 1 resulted in 1 floating ball and 1 Ru class sunk, trial 2 (the final kill) resulted in dealing 120 damage to the island demon.

Ultimately it's up to you which combination you want to use - 117 only, 118 only, 117 and 118, or neither. I went for the 118 method only. It depends on how much resources you have, how confident you are about your support fleet, and whether you're aiming for chipping down the boss health gauge or you're actually going for the boss kill.

Hope this helps!
