Here we are, taking a look at how Rosaline is as a fighter. After finding an ebony sword grasped in a skeletal hand (yes I'm using that easter egg as part of her character, big whoop wanna fight about it?) she began using it exclusively, for it had a superior balance and edge.
She fights whenever she needs to, but after the fight reactions are different depending on the enemy. Creatures like Trolls and the like get hardly a second glance, but people, even if they are ruthless Bandits, always get a moment of silence out of respect.
