デバフ

• Reading: デバフ
• Romaji: debafu
• Kanji breakdown: From English 'debuff' — de- (reverse) + buff (strengthen) → to weaken or apply a negative effect
• Pronunciation: /de.ba.ɸɯ/

Meaning

A debuff — a weakening effect applied to an enemy or a developer-imposed reduction in power for a game element.

The counterpart to バフ, デバフ refers to effects that weaken targets — reduced attack, lowered defense, slowed movement, and similar penalties. In RPGs and strategy games, applying debuffs to enemies is a core tactical element. The term can also describe developer balance changes that weaken something, though ナーフ is more commonly used for that purpose.

Examples

1. ボス戦ではまずデバフかけてから攻撃するのが基本。 The basics of boss fights: debuff first, then attack.
2. このキャラのデバフスキルがパーティーに必須だわ。 This character's debuff skill is an absolute must-have for the party.
3. デバフ重ねがけしたら敵の攻撃力ほぼゼロになった。 After stacking debuffs, the enemy's attack power dropped to basically zero.
