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'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, etcetera. 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 makes any action besides moving. The damage taken depends on the user's maximum HP. A burned Pokémon will have a flame next to it. 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 if they make any action. 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.

Freeze
When a Pokémon is frozen, it 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 will be 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 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 if they make any action. 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 sprint using "Shift". A paralyzed Pokémon will be seen shaking. 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 if they make any action. 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. The afflicted Pokémon will not take damage from using moves or items. A poisoned Pokémon will have a purple skull next to it. If an inactive 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 if they make any action. 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 party member. When put to sleep, a Pokémon enters its "sleeping animation" while Zs appear above it. The afflicted Pokémon is able to wake up manually by attacking enough times. 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 move Dream Eater, Ability Bad Dreams and take damage if afflicted with Nightmare, but able to use the moves Sleep Talk and Snore. Pokémon who hold a Dreamy Orb or use the move "Rest", the latter of which heals you upon using it, 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 or 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 moves 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.

Blind
When a Pokémon is blind, the entire map is darkened and they have no range of vision. The only way to blind a Pokémon is using Secret Power under the right conditions. Blindness lasts 20 steps. Pokémon who are blinded will have a blinking eye with an x over it.

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.

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.

Embargo
Pokémon under the effects of Embargo cannot use any items in their bag for five turns. A Pokémon cannot use Fling if it is under the effects of Embargo.

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

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 healing effects that they bring. Pokémon that are affected by Aroma Veil cannot be heal blocked.

Infatuation
Infatuated Pokémon cannot attack for five moves. Pokémon that have the Ability Oblivious or are affected by Aroma Veil cannot be infatuated.

Immobilized
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 Run Away Ability or is a Ghost-type, it will not be affected by immobilization.

Nausea
Nauseated Pokémon cannot use edible items. A Pokémon can become nauseated by consuming an Energy Root.

Nightmare
Pokémon afflicted by Nightmare cannot recover HP via Rest and lose 1/8th of their HP every turn they're asleep. If any member of the team holds a Lunar Wing, falling asleep while under the effects of Nightmare cures the effect.

Perish Song
If a 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 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 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.

Taunt
A taunted Pokémon cannot use status moves for ten moves. Pokémon that have the Ability Oblivious or are affected by Aroma Veil cannot be taunted.

Torment
A Pokémon that has been tormented cannot use the same move twice in a row. Pokémon that are affected by Aroma Veil cannot be tormented.

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 Thunderstorm Forest that are paralyzed.
