A Status effect is a temporary modification to a game character's original set of stats that usually comes into play when special powers, items and/or abilities are used, often during combat. Some of such modifications have a positive effect on the character, but most of the time they are negative. Positive status effects are usually referred to as buffs, while negative effects are referred to as debuffs (阻害効果(デバフ), Debafu?, lit. "obstruction effects"), which range to about 10-20 types.[1] Many attacks have a random chance of dealing negative status effects on opponent which are generally not curable, unless the appropriate crystals or potions are used. Most, but not all of them expire after a set period of time.

List of known status effectsEdit

Sword Art OnlineEdit

  • The Status bar of a player affected by a paralysis debuff, in SAO.
  • The Status bar of a player affected by a Body Part Loss Damage debuff, in SAO.
  • Protection of the Sound of the Wind buff icon
English name Japanese name Description References
Delay 行動遅延(ディレイ) A debuff that slows down the movement of affected players. Highly likely to occur if a player is being continuously hit by powerful attacks. [1]
Stun 行動不能(スタン) The most common debuff. It immobilises the player for up to ten seconds, disrupting player's next action. Can be randomly triggered by Sword Skills.[citation needed] Blurry yellow circles appear over the heads of affected players.

Stun has a probability of triggering a secondary debuff, called fumble (武器落下(ファンブル), Fanburu?), which causes the player's weapon to fall out of their hand.[1]

Paralysis 麻痺(パラライズ) Players affected by this debuff are rendered immobile for a long period of time. The minimum duration of the effect is ten minutes, though the duration of the effect may be longer, depending on the strength of the attack that triggered this status. [1]
Tumble 転倒(タンブル) A status unique to humanoid monsters that causes the monster to fall down and be temporarily unable to recover its standing. [3]
Luck Bonus 幸運判定ボーナス Increases luck, resistance to poison and paralysis attacks, the probability of fumble and tumble, and, potentially, the drop rate of rare items.

The buff can only be obtained by making an expensive offering at a church, equipping an accessory with such a bonus, or consuming a special food item.

Hate Attracts the attention of enemies, and causes NPC attacks to be focused on the player. It is automatically gained by being the most predominant attacker in a group. [citation needed]
Curse [citation needed]
Dizziness 眩暈 [6]
Blindness 盲目 [2]
Body Part Loss Damage 部位欠損ダメージ A debuff caused by a player's body part being severed. The duration of the debuff is short. [7]
