Yhorm the Giant is a boss in Dark_Souls_III. The Yhorm fight is part of every speedrun category in Dark_Souls_III. It is useful to know how to deal with it in an efficient way.
You always want to stay in front and close to Yhorm to bait one of 2 attacks, one of those is the stomp, the other is a slow slam. You also want to avoid doing the wind attack on uneven terrain like corpses/treasure piles and stairs, since the attack hitbox spawns at the bottom and these obstacles can block it, making the attack not deal any damage.
