Status Condition

Status conditions are effects that can be given to a Pokémon. These conditions can be afflicted by certain moves, Abilities, Orbs, traps, or certain tiles when stepped on. Pokémon can have immunities to certain or all status conditions through the use of moves, Abilities, Gems, family items, scarves, berries, and other held and consumable items. A Pokémon status condition can be healed through most of the same methods.

Non-volatile
Non-volatile status conditions will stay with the afflicted Pokémon until properly healed, like by eating a berry that heals the respective condition, or through using moves like Refresh, Heal Bell, or Aromatherapy. Pokémon with Hydration or Shed Skin can heal themselves without items, though the former requires it to be raining. Pokémon cannot be affected by non-volatile status conditions if they have the Comatose Ability. A Pokémon already afflicted with a non-volatile status condition also cannot be afflicted with another at the same time.

Burn
When a Pokémon that is inflicted with a burn makes any action besides moving, the Pokémon will take damage, and its physical attack will be halved. A burned Pokémon has an indicator of a small fire on the Pokémon. The damage taken depends on the user's maximum HP. Lava tiles will burn a Pokémon who is not immune to it if traveled over. Pokémon who hold a Flame Orb can also inflict the status condition on themselves if they make any action. If the Pokémon is capable of traveling on water tiles, stepping onto a water tile will heal its burn if it has one. Fire-type Pokémon are unable to be afflicted with this condition.

Freeze
When a Pokémon is frozen, they will be unable to move or act for a random amount of turns, but can still be switched out by another team member. A Frozen Pokémon has an indicator of being encased in a block of ice. The afflicted Pokémon is able to unfreeze manually by attacking enough times. Tiles such as the water found in Deep Winden Forest can freeze a Pokémon who is not immune to it if traveled over. Pokémon who hold a Freeze Orb can also inflict the status condition on themselves if they make any action. Ice-type Pokémon are unable to be afflicted with this condition.

Paralysis
When paralyzed, a Pokémon will sometimes fail to use attacks or items and are unable to sprint using "Shift". A paralyzed Pokémon has no indicator, but the Pokémon's sprite can be seen shaking.The Petrify Orb item can inflict paralysis on every enemy Pokémon that is nearby the user. Tiles such as the water found in Voltaic Rainforest can paralyze a Pokémon who is not immune to it if traveled over. Pokémon who hold a Static Orb can also inflict the status condition on themselves if they make any action. Electric-type Pokémon are unable to be afflicted with this condition.

Poison
Poisoned Pokémon will take damage every two-three tiles they move. The afflicted Pokémon will not take damage from using moves or items. A Poisoned Pokémon has an indicator of a purple skull on the Pokémon. A Pokémon that is not currently active, will not take damage if another party member moves around the floor/map. Tiles such as the water found in Caustic Sewers or a Poison Trap can poison a Pokémon who is not immune to it if traveled over. Pokémon who hold a Toxic Orb can also inflict the status condition on themselves if they make any action. Pokémon that are Poison- or Steel-types or have the Ability Immunity are unable to be poisoned, but Pokémon with Corrosion are still able to poison Poison- and Steel-types. Pokémon that have Poison Heal as one of their Abilities can still get poisoned, but will be healed instead of harmed.

Sleep
Sleep acts like being frozen: a Pokémon will be unable to move or act, but can still be switched out by another party member and the afflicted Pokémon is able to wake up manually by attacking enough times. When put to sleep, the Pokémon enters a "sleeping animation" while Zs appear above the Pokémon. Unlike being frozen, or any of the other non-volatile conditions, being asleep makes the Pokémon vulnerable to moves like Dream Eater. The player can inflict this condition on themselves through the use of a Dreamy Orb or through the move "Rest", the latter of which heals you upon using it. The Slumber Orb item can inflict sleep on every enemy Pokémon that is nearby the user. While there are no tiles that can trigger this condition, stepping on a Slumber Trap can inflict this on a Pokémon. There are no types that are immune to being put to sleep, but Pokémon who have the Insomnia or Vital Spirit Ability, or have been hit with Uproar can not be put asleep.

Volatile
Volatile status conditions will only last for a given amount of time that a player has not transitioned to the next map/floor or wear off after a certain number of moves.

Confusion
When a Pokémon is confused, it will have a chance to inflict damage on itself if it uses an attack or item. In addition, the movement of the Pokémon will be scrambled, causing it to move in a random direction when moving. Confused Pokémon will have an indicator of three ducks running around them. Besides certain moves, Pokémon can become confused when stepping on a Spin Trap. Pokémon that have the Own Tempo Ability or are equipped with a Persim Band are immune to being Confused.

Cringe
Cringe is a one-turn status condition that prevents a Pokémon from attacking. Pokémon with Inner Focus are immune to cringing while Pokémon with Steadfast will still cringe, but will gain Speed each time they do.

Embargo
Pokémon under the effects of Embargo cannot use their held item or any items in their bag for five moves. The Pokémon cannot use Fling if it is under the effects of Embargo.

Heal Block
Pokémon that are affected by Heal Block will be unable to heal for five moves. Moves that heal will not work and are unaffected by the effects of Wish, Ingrain, Aqua Ring, Leech Seed, or Heal Pulse. While under the effects of Heal Block, a Pokémon can still use items like Oran and Sitrus berries, but will not be provided the effects that they bring.

Immobilized
Pokémon that are Immobilized will be unable to move and cannot be switched until the effect is gone. If a Pokémon is holding a Shed Shell or has the Run Away Ability, it will not be affected by Immobilization. The Pokémon can escape from being immobilized if it uses U-turn, Volt Switch, or Baton Pass or it will escape if hit by any move that throw the target in a certain direction, such as Roar or Dragon Tail.

Perish Song
If the Pokémon is affected by Perish Song, it will gain a "Perish counter". The counter will start at three and will decrease by one every time the Pokémon uses a move or an item. The Pokémon will faint when the counter hit zero. The Perish counter will not go down if the Pokémon is switched out. Pokémon who have a Perish counter active will have the indicator of a red skull. Pokémon that have Soundproof as an Ability are unable to be affected by Perish Song.

Torment
A Pokémon that has been Tormented cannot use the same move twice in a row. If the Pokémon is holding a choice item or has only one move that still has PP left, it will be forced to use Struggle every second turn.
