Is there a way to recruit Lucil'ianna? Coz I don't wanna fight or kill her.
Yes you can! You'll need to defeat her in the tavern after rescuing her. Then there's a quest in Lady Lake to recruit her
Rescue her? Like... In the beginner/tutorial area? Coz the walkthrough only says "encounter an elf."
Scroll down further and find the "Pure of Heart/ Recruit Lucill'ianna" header!
