So been playing Valkyrie a bit now and one thing I've started noticing is that when you do your shield slam and then the spin knockdown move, they recover fast enough to dodge the knockdown. The knockdown's hitbox seems to be broken as it obviously hits a lot of the time but the spear just goes straight through their legs when they dodge. People keep telling me "this isn't dark souls, you can't dodge in the same way", so why does it work like that with this specific attack?
