Monsters and Stun or KO

The following Monsters or Effects cause Stun or KO Status:

  • Tzitzi-Ya-Ku 
  • Diablos 
  • Being struck by strong attacks, especially attacks with high knockback.
  • Getting knocked down multiple times over a short period.

The effects of stun are different between monsters and hunters. Hunters are simply immobilized, whereas monsters are put into a confused state, or are knocked down.

If a hunter is stunned you are temporarily immobilized until the effect ends, or when interrupted. Any friendly hunter, palico or monster can hit you to interrupt the stun.
Once stunned, you can wiggle the analog stick to very slightly decrease the time spent stunned. A more effective way is to use the Signal command (which can be assigned in the radial menu). Using the Signal command will call your palico to your side, increasing the chance it'll decide to hit you out of stun.

A monster is stunned when hit on the head multiple times by blunt force, such as with a hammer or hunting horn. Some bladed weapons have blunt attacks in their move sets, such as the Sword and Shield's shield bash. Often times when stunned the monster will fall over. When stunned, monsters temporarily lose the ability to target enemies, and will blindly attack or run around, if not stand still. Flying monsters will be grounded, 

The following Monsters are weak to Stun or KO Status:

        How long does stun affect hunters?? Like, how many seconds? And how long does it last when moving the left analgo stick? Might have to figure this out myself...

          This is by far the most bull$&/@ mechanic in this game. Also stun seemingly isn’t exclusive to just some monsters. From what I can tell if you get hit enough by a large monster you’ll get stunned. I have been stunned from pukei-pukeis to legianas. This mechanic essentially allows you to die to random chance. Get stunned on low health and, “OH LOOK I CANT DODGE THE CHARGING MONSTER” it is so annoying to be grinding a monster for materials and then die to random chance because stun decided to proc at the worst possible time. Not to mention it just makes the grinding take longer because you LOSE REWARDS ON DEATH. All I can do is hope that this mechanic is removed in future monster hunter titles. Does stun make sense realistically? Yes. Is it extremely annoying? Triple yes.

            If weakness is considered by 3 stars - Great Jagras, Jyuratodus, Rathian, Paolumu, Pink Rathian, and Uragaan are all 3 stared to stun.
            If it also involves 2 stars then you can add: Kulu-Ya-Ku, Pukei-Pukei, Tobi-Kadachi, Anjanath, Tzitzi-Ya-Ku, Great Girros, Radobaan, Legiana, Odogaron, Rathalos, Dodogama, Deviljho, Lavasioth, Azure Rathalos, Nergigante, Teostra, Lunastra, Kushala Daora, and Vaal Hazak.
            Mainly, MOST of the monsters in this game are fairly vulnerable to Stun...Unsure if this is why they are not listed here but surprised no one has made any mention of this since the game came out and no one edited this page to at least include the 3 star weakness monsters to this.

              It'd be nice if severe environmental damage was capable of waking you from stun. I dunno about you guys, but I imagine that if I got knocked into a pool of lava or acid, it wouldn't matter how dazed I am; the whole "I'm on fire" thing would provide a solid jolt to the system. There's nothing worse than getting stunned from a light thwack and then watching your avatar obliviously melt in a sea of flames.

                Just wear tzitsi Gauntlets with one steadfast jewel to never get stunned again. Or 3 jewels. I can't see myself hunting without it
