there will ever be strategies to guard break the opponent?
F Wara fireballs are meant to guard break, F Maids have mostly airtight constant blockstring that needs to be bunkered or you have to take a hit to get out.
i also noticed something strange (H-Moon) that it might be not true: when you shield, but your shield doesn't collide with an hit, the guard bar becomes of another color, and weaker too
Dodging weakens guard bar color, and shielding. EX Shielding does not. Half Moon/Full Moon can never EX Shield so when they shield it will always weaken their guard bar.
there already is Van, Fmaids and Fwarc are testament to that.
Whiff Shields and Whiff Dodges both reduce the level of your guard bar.
Doesn't need to be whiff. All Dodges and normal Shields reduce guard bar. If you actually land a shield it might reduce less guard bar than if you whiff it though.
Is it only whiff shields? At one point I saw C form shield successfully and it still went down. Maybe because they only got a normal shield instead of an EX shield, but I don't really remember if they got norm or ex vers. I didn't realize that evading lowers it as well.
Also it seems that guard break lasts about a full second.
That would be normal. C/F Guard bar also weakens much slower than H. Two airdodges in Half and it already starts turning red. I think if Half does one dodge and one shield it instantly turns bright red. You can airdodge all day with Crescent and your guard bar will just go gray/blue.
Anyone know if the color of you guard bar has any effect on the stun time?
I don't think so. Guard Break might also not be a set time and could be like Stun in most games where rotation the stick reduces the time.
