Negative Status Effects (Afflictions)
These can be negated by using certain armor skills. Some monsters can resist status effects, with most of them being resistant to status effects that they themselves can deal out. For example a monster that does poison damage is immune to poison damage.
The more times a monster is effected by a status it will become more resistant to that status. Some monsters gain resistances faster than others. See Elemental Resistances for a full list of how that works.
Poison - Poison will slowly drain the hunters health but can be cured using a antidote. You can tell if a monster has been poisoned by the purple goo drooling from it's mouth. Some monsters inflict Deadly Poison. It drains your health more rapidly than regular poison but is cured by antidote too.
Sleep - After taking enough sleep damage the hunter will fall asleep in the middle of battle. If enough sleep damage is dealt to the monster it will go to sleep. This can be cured by getting hit by a friendly hunter, a small monster, or even the big monster itself. Sleeping monster and hunters take greatly increased damage, but only for the first hit, as it will then wake them up.
Paralysis - This will immobilize a hunter or monster for free hits. The hunter and monsters will have yellow shock waves pass through their body when paralyzed. Hunters will fall to the ground, and will be unparalyzed if anything hits them. Monsters will remain standing, but will remain paralyzed even if something hits them. Paralyzed monsters and hunters take increased damage.
KO - When a monster lands several hits the hunter may become stunned. Often times the only way to recover is by getting hit or repeatedly pressing buttons on your controller. 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.
Slime / Blast - If a monster with the slime status hits a hunter it will apply slimeblight. If hit again or enough time passes the hunter will take blast damage. This can be avoided by rolling or using Deodorant. When attacking a monster with the slime/blast it will apply the status and explode after several hits.
Felvine Scented- This status ailment can only be inflicted by a hunter using a Felvine Bomb. Any target, friend, foe, or neutral, hit with the bomb will be covered in a pink smoke. All nearby felynes, melnynxes, and wild cats will attack the target until it wears off.
Negative Status Ailments: Hunter Exclusive
These are status ailments that monsters inflict on the hunter. They can be cured by waiting, using certain items, or other means.
Defense Down: The hunter's defense is lowered. Can be cured by any defense increasing item, like Armorskin, or by waiting.
Stench: The hunter has been hit with soemthing foul, and a stench cloud hangs around them. It prevents the hunter from eating anything, like potions, rations, etc. It can be cured by waiting or using a deodorant.
Frenzy Virus: The hunter has contracted the Frenzy Virus from a Gore Magala, a Chaotic Gore Magala, a Shagaru Magala, or any infected monster. The virus has two stages, an incubation stage and a mature stage. During the incubation stage a purple bar will appear near the hunter's name, and slowly start to fill. The only way to decrease the bar is to eat a nulberry, but this will not get rid of it. If the bar fills, the virus goes into it's bad mature stage. In the bad mature stage, hunters take extra damage from frenzy attacks and has no natural recovery. The only way to get rid of it is to wait. If the hunter deals enough damage before the virus meter fills, they go into the good mature stage. In this stage, the hunter has +15% affinity and is immune to reinfection until it wears off.
Snowman: The hunter has been incased in snow and ice. They are slowed to a walking pace and they are prevented from using most items or attacking. It can be cured by waiting, using a cleanser, or getting hit.
Muddy: The hunter has been covered in thick mud. Has the same effects and cures as snowman.
Bleeding: The hunter has been hit by something very sharp and jagged. They take small amounts of damage whenever they roll, sprint, or attack. It can be cured by waiting, eating a Well-Done Steak, Mosswine Jerky, or Sushifish, or crouching without moving for a short time. Curing Bleeding will give Increased Natural Recovery for a short time.
