Pov Diana's:
I, Beatriz, and Érica are going to the second floor of the castle, we are going to the place where there should be a meeting room, Beatriz says she saw through one of the windows earlier that there were many enemies there.
On the way, Beatriz and I killed the enemies faster than Érica could cast her magic.
I sliced enemies to pieces with quick attacks while Beatriz always aimed at vital points killing enemies with single attacks.
As we went to the second floor we kept looking inside the doors to make sure we didn't have any more enemies, on the way we found some weak Demons and Vampires, it seems they were sent to explore and fight us.
The strongest enemies must be using these little fish to make us expend our energies on the chance to facilitate their own battles, this is a simple strategy more effective in most situations.
