Debuff  负面效果

		This article or section is outdated. Please update this article to reflect recent events or newly available information. 本文章或章节已过时。请更新本文以反映最新事件或新可用信息。

A debuff is any status effect given to a champion, minion or monster that negatively impacts their combat performance in some way. The inverse is called a buff. Among other things, debuffs can directly lower a unit's statistics, cause damage over time or be triggered with subsequent attacks for additional effects.
防御负面效果（Debuff）是指对一个英雄、小兵或怪物造成的某种负面状态效果，会以某种方式对其战斗性能产生负面影响。与之相反的是增益效果（Buff）。防御负面效果可以直接降低单位的属性，造成持续伤害，或在后续攻击中触发额外效果。

All forms of crowd control fall under the debuff classification as they inhibit a unit's ability to fight directly, but debuffs that consist solely of crowd control are not listed here due to their prevalence and relative importance in gameplay. See the crowd control page for details.
所有形式的 群体控制都归类于防御负面效果，因为它们直接抑制了单位的战斗能力，但由于群体控制效果在游戏中普遍存在且相对重要，因此仅由群体控制组成的防御负面效果不在此列。详细信息请参见群体控制页面。

Unless otherwise stated, debuffs cannot stack with themselves, with repeated applications upon the same target simply causing the debuff duration to reset and not incurring increased effectiveness. All debuffs are either temporary or conditional and do not persist after the affected target's death.
除非另有说明，防御负面效果不能叠加，对同一目标重复施加效果时仅会重置持续时间，而不会增加效果强度。所有防御负面效果都是临时的或有条件的，不会在受影响目标死亡后继续存在。

Resource expenditure linked to ability usage (such as with most mana- and energy-using champions) is not considered to be a debuff. Abilities with certain tradeoff mechanics (such as the increasing mana cost and damage of Kassadin's Riftwalk or the decreased attack range in Nidalee's Cougar form) are also not considered to be debuffs.
与技能使用相关的资源消耗（如大多数使用蓝量和能量的英雄）不被视为防御负面效果。具有某些交换机制的技能（如 卡萨丁的 虚空行走中增加的蓝量消耗和伤害，或 奈德丽在 猎豹形态下减少的攻击距离）也不被视为防御负面效果。

There are currently 5 sources of debuffs: champion abilities, summoner spells, item effects, Rune Effects, and neutral monsters.
目前存在 5 种减益效果来源：英雄技能、召唤师技能、物品效果、符文效果和中立怪物。

Crowd control

A unit that is disabled is affected by a status effect that prevents certain actions – such as movement, attacking, casting and/or seeing–blocked, reduced or controlled.

Crowd control applied by one's self or an ally cannot be countered in any way, neither reduced in duration, resisted, nor removed unless special cased to do so.

• The crowd control effect may still be cleansed if it is applied as a debuff separate from the originated ability.
