Ghost of Tsushima: Red X-Shaped Attacks

Ghost of Tsushima's Red-X Shaped Attack is a mechanic that alerts you of incoming damage from an enemy that can be dodged. This damage can come in the form of an attack through a weapon or a shield. 

This kind of attack has a very obvious visual alert, that you can use to punish the enemy through proper counter actions.

First is the attack wind-up, where the red x-shaped glint becomes visible.

Then you perform the actual dodge, leaving your attacker in a state where he can be punished.

And finally, the punishment for your target, typically done through a Quick attack.
