Complete list of buffs and debuffs

RAID Shadow Legends has a lot of positive effects (called “buffs”) that can be applied on a Champion, as well as lots of negative effects (called “debuffs”). Knowing what does which buff or which debuff will help you build a team depending to tackle the situation you are in.

Buffs

A buff is the common name given to any positive effect applied on a target in a RPG. In RAID Shadow Legends, buffs will always be represented inside a blue square. Each buff has a specific icon helping you identify the enhancement applied.

• 
  Ally protection

• 
  Block damage

  Makes the Champion immune to all forms of damage.
• 
  Block debuffs

  While this buff is active, the Champion is immune to all debuffs. Instant negative effect such as Decrease Turn Meter are not affected and work as normal.

  Continuous Heal

  Heals the target Champion by 7,5 / 15% of their MAX HP at the beginning of their Turn.
• 
  Counterattack

  When attacked, the Champion with this buff strikes back at their attacker using their Default Skill. This attack deals 75% of the normal Default Skill damage.

  Shield

  The Champion’s HP bar is reinforced for X Turns with a Shield effect. Damage is calculated normally but is first applied to the Shield (unless the attack ignores Shields, which is stated in the Skill description). When the buff expires or Shield value reaches 0, the Shield is removed and further damage applies as normal. Note: damage dealt to the shield does not count as damage dealt to the Champion, so effects such as Lifesteal do not benefit from it.
• 
  Unkillable

  The Champion with this buff cannot fall below 1 HP for the entirety of its duration.

Debuff

A debuff is the common name given to any negative effect applied on a target in a RPG. In RAID Shadow Legends, buffs will always be represented inside a red square. Each debuff has a specific icon helping you identify the effect applied.

• 
  Block Buffs

  All buffs that are applied to the Champion with this debuff are automatically blocked and have no effect.

• 
  HP Burn

  While the debuff is active and at the start of the affected Champion’s turn, they and all their allies take damage equal to 3% of their respective MAX HP. There can be only one [HP Burn] debuff active of a Champion at a time. However, if multiple Champions on the Team are debuffed with [HP Burn], all of these debuffs work as normal and apply their full damage. This debuff is often looked for to increase Clan boss damage. Indeed, it has a lot of HP, hence damages based on MAX HP are insane for this fight.
• 
  Leech

  Any Champion that attacks a Champion with this debuff heals for 10% of inflicted damage.
• 
  Poison

  Damages the target Champion by 2,5 / 5% of their MAX HP at the beginning of their Turn. This damage is not affected by any other effects and only scales in accordance with the Target’s MAX HP. Block Damage blocks it. If the Target Champion has a Shield, Poison damage will be applied to the Shield first. This is one the other debuffs that is often looked for to perform in the Clan boss encounter. Reasons are the same than the [HP Burn](#debuff-hp-burn) one: it has lots of HP.

• 
  Sleep

  The Champion with this debuff is unable to act X Turns. Cooldowns are not refreshed while [Sleep] is active. Continuous Heal and Poison Effect work as normal while the Champion is debuffed with [Sleep], so do any Passive Skills that heal the Champion. Any incoming damage that the Champion receives automatically removes [Sleep].
• 
  Stun

  The Champion with this debuff is unable to act X Turns. Cooldowns are not refreshed while [Stun] is active.
• 
  Weaken

  Increases damage received by the Target Champion by 15 / 25%.

Minotaur

Some buffs and or even debuffs are only available during the fight against the Minotaur. They mostly act as huge damage multipliers, both for him and for you.

• 
  Minotaur Buff: Rage

  While active, this buff increases the damage the Minotaur deals by 400%. If the Minotaur is under this buff, you should try to prevent direct hits as much as possible.
• 
  Minotaur Debuff: Dazed

  While active, this debuff increases the damage the Minotaur receives by 200%. The duration of this debuff cannot be increased. This is the “key” moment of the Minotaur fight: use all your cooldowns during this turn, and make sure you beat the crap out of him!
• 
  Minotaur Debuff: Hex

  Minotaur's [Tremor Stomp] Skill deals double damage to Champions with this debuff. Paired with the “Rage” buff he has during the fight, this leads to a 800% damage multiplier for the Minotaur.
