Status Condition

Status conditions are effects that can be given to a Pokémon. These conditions can be afflicted by 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's 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, through using moves like Refresh, Heal Bell, or Aromatherapy, et cetera. Pokémon with Hydration, Shed Skin or Natural Cure can heal themselves without items. 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
A Pokémon that is inflicted with a burn will have its attack stat halved and take damage when it takes a turn. The damage taken depends on the user's maximum HP. Lava tiles, burning water such as the water found in Sauna Cavern, or a Flame Trap 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 when they pass a turn. If the Pokémon is capable of traveling on water tiles, stepping onto one will heal its burn if it has one. Pokémon that are Fire-type or have the Ability Water Bubble are unable to be burned. Pokémon with the Ability Guts will not be affected by the Attack reduction if burned.

Freeze
When a Pokémon is frozen, it will be unable to move or act, but can still be switched out by another team member. An afflicted Pokémon is able to unfreeze by passing turns. How many turns freeze lasts depends on how the condition was caused. Tiles such as the water found in Deep Winden Forest or a Freeze Trap 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 when they pass a turn. Pokémon that are Ice-type or have the Ability Magma Armor are unable to be frozen.

Paralysis
When paralyzed, a Pokémon will sometimes fail to use attacks or items and is unable to run using 🇧🇹. Petrify Orbs will inflict paralysis on every enemy Pokémon that is nearby the user. Tiles such as the water found in Voltaic Rainforest or a Static Trap 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 when they pass a turn. Pokémon that are Electric-type or have the Ability Limber are unable to be paralyzed.

Poison
Poisoned Pokémon will take damage every two-three tiles they move. An afflicted Pokémon will not take damage from using moves or items. If a Pokémon is poisoned, it will not take damage if another team 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 when they pass a turn. Pokémon that are Poison- or Steel-type 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
Sleeping Pokémon will be unable to move or act, but can still be switched out by another team member. An afflicted Pokémon is able to wake up by passing turns. How many turns sleep lasts depends on how the condition was caused. Slumber Orbs will inflict sleep on every enemy Pokémon that is nearby the user. Being asleep makes Pokémon vulnerable to the moves Dream Eater, Nightmare, and the Ability Bad Dreams, but able to use the moves Sleep Talk and Snore. Pokémon who hold a Dreamy Orb or use the move Rest can also inflict the status condition on themselves. Stepping on a Slumber Trap can inflict sleep on a Pokémon. Pokémon that have the Ability Insomnia, Vital Spirit, or have been hit with Uproar can not be put asleep.

Volatile
Volatile status conditions will typically only last for a given amount of steps or turns unless properly treated with a consumable item that cures volatile status conditions. Unlike non-volatile status conditions, volatile ones will wear off upon changing floors or maps.

Bound
Bound Pokémon will be immobilized for three turns, losing 1/16 of their HP rounded down each turn. This effect is only caused by moves such as Sand Tomb, Whirlpool, Fire Spin, Infestation, etc. If a Pokémon is holding a Shed Shell, has the Ability Run Away or is a Ghost-type, it cannot be bounded.

Blind
When a Pokémon is blind, the entire map is darkened and they have no range of vision. Blindness lasts 20 steps. The only way to blind a Pokémon is using Secret Power under the right conditions or hold Y-Ray Specs. Some family items can also inflict blindness.

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 can still cringe, but will gain one stage in Speed each time.

Curse
Pokémon under the effects of Curse will lose 1/4 of their HP when they attack.

Drowsy
Drowsy Pokémon will fall asleep for three turns, two turns after becoming drowsy. The move Yawn will make an opponent drowsy, and certain items such as Herbal Tea.

Encore
Pokémon under the effect of Encore can only use the move they last used for five turns. The move Encore fails if the target has not yet executed a move. Pokémon that are under the effect of Aroma Veil cannot be encored.

Exposed
When a Pokémon is exposed, it can be affected by moves of types it is normally immune to and attacks against it will ignore boosted Evasion. The moves Odor Sleuth, Foresight, and Miracle Eye will expose a Pokémon.

Grudge
When a Pokémon has the Grudge status, it will deduct all PP from the move last used on it when it faints. It lasts until the Pokémon is hit twice. A Pokémon obtains the Grudge status from using the move Grudge. A Grudge Trap will also spawn Pokémon with the Grudge status.

Grounded
Grounded Pokémon lose mobility and Ground-type immunity from being Flying-type or the Ability Levitate. Pokémon will become grounded from the move Gravity, by holding an Iron Ball, or being hit by the move Smack Down. A Pokémon can become ungrounded from using the moves Magnet Rise, Bounce, and Fly, or being hit by the moves Telekinesis and Sky Drop.

Heal Block
Pokémon that are affected by Heal Block will be unable to heal for five turns. While under the effects of Heal Block, a Pokémon can still use items and moves that heal, but will not be provided the healing effects that they bring. Pokémon that are under the effect of Aroma Veil cannot be heal blocked.

Infatuation
Infatuated Pokémon cannot attack for five turns. A Pokémon can be infatuated from the move Attract, a Love Potion, or Cute Charm. Pokémon that are the same gender or genderless, have the Ability Oblivious or are under the effect of Aroma Veil cannot be infatuated.

Immobilization
Pokémon that are immobilized will be unable to move and cannot be switched out until the effect is gone. If a Pokémon is holding a Shed Shell, has the Ability Run Away or is a Ghost-type, it will not be affected by immobilization.

Landed
When a Pokémon uses the move Roost, it will give them the landed condition. Pokémon that have landed on the ground lose their Flying type and cannot travel on water, fire, or air for a certain amount of turns.

Perish Song
Pokémon affected by Perish Song will gain a "perish count". The counter will start at three and will decrease by one every time the Pokémon uses a move or an item. The Pokémon will have its HP reduced to 1 when the counter hits zero. The perish count will not go down if the Pokémon is switched out. Pokémon with the Ability Soundproof are unable to be affected by Perish Song. Safeguard also prevents Perish Song and the counter from decrementing.

Trivia

 * Pokémon such as Zangoose who have an Ability that benefits from a status and an Ability preventing it allow the respective status to bypass the immunity.
 * In certain dungeons, Pokémon can spawn already afflicted with a non-volatile status condition. For example, it is possible to find Pokémon in Winden Forest that are frozen.
