How would you guys build Legendary Lyn?

well if i got her optimal ivs which are probably +atk/+spd -hp/-def, i would probably just give her either moonbow or luna for special, and then fill in her gaps with a spur or hone.

just add desperation, moonbow, and repositon with either a heavy blade or a spd+3 seal. she seems to be the best offensive archer in a long time potentially better than bridal cordelia but with worse brave bow synergy.

Not planning to roll for her but if somehow I got one, maybe with the basic kit on. With +spd IV, when someone initiate combat on her she will have 48 speed, with decent defensive buffs as well so try to ORKO her if you can. In arena defense team, she got dual rally skill so AI will always stay near her allies and that will probably shut down most of the player phase units (except brave weapons and a certain liar who told me magic is everything). Basically to make the opponents life a bit more difficult that is.
