Hi, i'm a new player and I have some questions about SED and Event : How it works ?

I notice au 6 focus attack do as much damage on Elite Gard than your total seduction. What about 1 focus attack ? And wat about the bonus SED during Event ?

Another question : Should I take 6 N-Gacha ticket or 6 N-Wild Cards with my Pero ?

Thank you !

(Any advice for gain power faster ? Without using $)
