both 3 are good. The problem is that they fill pretty much the same role (duelists) , and while having 2-3 good duelists is good , you could have rnged something else.


That being said , celia is a defensive barbarian , and can make a good solo tank for bosses with her huge hp pool and defensive skill. Also she boosts a good passive.


Then tethis had a bit lower damage , but she doesn't lose her defense compared to dahlia , and has a better awakening IMO , so i'd go with her (between the 2 valks) if i were you
