Their fight quickly dissolved into Eldrian running and dodging for his life while Vivian and Ceph tried to do enough damage. Elizabeth continually cast a speed boost on Eldrian while helping out against the undead where needed the most. Divine spells were far more effective than any other.
It didn't take long before the undead completely filled the area that they were fighting in. As a result, Vivian and Ceph had to fight simply to stay alive. Eldrian had to just keep running.
Luckily, these skeletons and zombies weren't a threat to him thanks to his agility-focused build he could wave between them with ease. And luckily the Vodi was also not all that agile. It could reach great speeds when running straight, but it could not make a turn to save its life.
