Manel or whatever your name is,get solid proof and don't talk about what you don't know.Far from I've noticed,you know shit about this issue,so you'd better stay shutted and gather some information,then,you can come argue with us.
They don't ''Normal Attack''. They just Sonic Blow without any previous ''Normal Attack''.3 Kiels,195 ASPD. That's far from possible to spam 7 Sonic Blows at once.Hacks?I don't know,I've got no SOLID proof on it,and I which I could but in my position I can't do shit but to watch closely their moves and make my own theory.Far from I've seen,7 sonic blows is pretty impossible.
I really never tried it out,since I'm pretty lazy to roll Sonic Blow,but I've tested with my High Priest,and with ULTIMATUM spam I've done 5 heals at once.I don't know Heal/Sonic Blow formulas so I can't really compare them and check delays/whatsoever.
By the way,Entropy or whoever is testing the sonic blow spam,I advise to get all the buffs in game ((WS,HP,SL,etc)) because that's what they do. Maybe including these foods that give extra status.
