Demon Slayer , pro come please =(

* i hear people say addition potential +wa better.
but i think my eq all from [gacha magic box]
with high str , so the addition potential +str% is better ?

# i got a screenshoot is a cannon weapon, addition potential [Unique]
and have Total DMG 9%
that mean when [Legend] can be 12%


so , str % > wa ? when high STR and high STR%
