Continuing to struggle with the slime, Scaly thought about all sorts of ways that she could use her water magic to reach the core of the slime, but in the end, all of them would require her to gather her mana for an extended period of time. Time that she didn't have with constantly having to stop the slime from getting too close to any dangerous areas on her body.
