The approach to this battle is vastly different than typical party or solo situations. Dancers normally reserve TP to keep a party or themselves alive and buffed; the battle with Laila is about killing quickly and relying on external factors to keep the Dancer alive and buffed, as if the Dancer were a pure damage dealer instead of a supporting job. Trying to win this battle with the idea that you will outlive her through typical Dancer means will most likely result in failure.
