Strange. This only happened to me ones in an optional boss fight at the very start of the game where he can one shot you. Main story bosses are quite generous in damage, you don't die straight away.
Are you guys equipping right Pictos? Make sure to always prioritize health above all. If you have around 300-500 health, then you must have gotten few 350+ health Pictos by now. Double the health!
If there had been other games of similar scale showcasing the richer or at least half-decent side, I too would've gladly joined you. However, for some reason, almost every first major entertainment product from our country tends to focus on the less appealing aspects. There needs to be some balance.
Yeah that turtle boss was one of them, his winter attack is way too op, I couldn’t parry, just kept dodging it. Hard to parry against the enemies I’m facing in stonewall cliffs in general, just dodge !
