Burn Fionn or use him in my arts farming team
so i got spooked by Fionn should i burn him and beowulf for the anniversary blonde
Burn Fion! Burn him! Worthless twerp who came twice when I wanted tama or kiyohime lancers.
Not sure I would spend on a mystic code though. I never used any other than the combat uniform these days. Though anniversary blonde is the cutest one... (not biased at all with the same outfit in my cosplay lineup :-D)
His first skill post ST quest (not out yet, I think) make he become a somewhat decent support for arts crit teams.
Also, you can use his taunt as a kill-switch, since it's not worthy of levelling (big cooldown, need a lore to be not-RNG) =D.
AOE Lancer is a kinda uncommon niche, but in the second Christmass of this year you will be getting a AOE Lancer easy to NP5, and better than Fionn overall.
Just use him if you really want an Arts Lancer and does not have Li Shuwen to take this job.
