She threw fireball one after another and extinguished the flames that fell on the ground as they came. What was beneficial was that this barely used spiritual power so she wasn't the slightest bit tired. Compared with coating one's sword with spiritual power, this technique was like a single drop of water in a vast lake. And unlike arrows and other of her throwing weapons, she didn't need to aim too seriously, though its also to the merit of the Vampiric Bats for coming in droves. The damage it caused was also on another scale. She just needed to throw them at a mass of bats and it would immediately cause harm to at least twenty of them. If she had to say, the effects were even better than her bombs since the shrapnel from them couldn't always kill her opponents, but the flames guaranteed a kill as long as it landed, even at a nonvital spot.
