Unflinching is the little yellow helmet icon. It means that you will no longer get hitstun from attacks - you still take damage, but your character wont react to getting hit, meaning you can catch opponents in combos even if they're attacking you. You'll probably run into this ability a lot against Armed Forces Cerebella, Untouchable Peacock and all forms of Sekhmet. At first, this might seem incredibly broken and hard to beat because you are suddenly unable to combo people. However, there's a pretty simple solution you can use to circumvent it: Grabs. Grab like there's no tomorrow! Throws are a special form of attack that don't cause hit stun. They put enemies into a thrown state instead, so unflinching is completely ignored. Equip a stack of grabs onto your character, and every time you see that helmet, stop attacking with regular hits and exclusively use grabs. Hopefully this sneaky little tip will help you past that double Armed Forces Cerebella mission in Ascent of a Woman!
