Just got a +HP/-DEF Lewyn earlier and I want to use him but I don't know what kind of build I could do.
If you got any ideas tell me.
Flashing Blade works as his seal too but I’ve currently got that on my Ishtar. His base skill kit is perfect as his so he doesn’t really require inheritance so his base Glimmer/Swift Sparrow work over Dragon Fang/Life and Death too if you’re not looking for an expensive set. Mine is Def+, HP- so this definitely works for non perfect IVs.
You shouldn't really worry about decreasing his Def and Res. Lewyn is a one-trick pony who works best during the Player Phase. I can't stress this enough: as long as you're using him correctly (during Player Phase), he shouldn't be tanking any hits at all.
Of course, if you're on a budget Swift Sparrow works fine but L&D 3 is optimal IMO.
Lewyn can't really do much in Enemy Phase, and would rather attack than be on the defensive side. He is literally made to nuke enemies in one turn, so why not make him do it better? It might just be my mindset, though. So you do you.
Still, I personally think 25 Res, by today's standards, is still pretty low.
His base kit and any assist (besides the ones that give health away) works perfectly well on him. You can give him Life and Death, but Swift Sparrow by default is a good option as the difference is 1 point of attack and speed. He doesn't need a seal to perform extremely well.
