Managed to pull +atk -speed lyn but i already have neutral one should merge her with the neutrel one?
B!Roy +Res -HP
B!Roy +Atk -Speed
With one should i keep?
Whew. That's a tough one... +ATK is highly preferred on him but -SPD causes him to miss some critical doubles. I'd probably still go with +ATK...but try to patch the -SPD up with his other skills and team support.
But an argument could be made for -HP +RES because it leaves his offensives intact. The annoying thing is that it doesn't really do anything else for him. 27 RES isn't going to proc Ploy skills. Plus it's -4 HP. Ugh.
I missed the first part of your question... For Brave Lyn, personally I'd keep both and run them with different builds.
Neutral: Her default kit.
+ATK -SPD: Brave Bow+
But if you want to merge them or use one for skill inheritance, I'd recommend sticking with Neutral and her default kit.
Her default build is actually sufficient for taking out mages. She is able to ignore bladetomes and their buffs, and with her decent res of 28, she will be able to duel mages really well. The extra mobility and physical ranged damage that she dishes are also good for maneuvering around and killing mages. You just need a counter for tank raventome users (maybe another mage unit) to keep B Lyn from facing counters
