Buffs, Debuffs and Instant Effects
Updated for December 2021
Within Raid: Shadow Legends, champions and bosses can apply a number of buffs, debuffs and instant effects that impact your champion’s ability to perform their role. There are 3 main effects:
- Buffs – Effects you can place on your allies to improve their abilities
- Debuff – Effects you place on your enemies to reduce their abilities and for them to take more damage
- Instants – Effects you can activate instantly on your allies or enemies i.e. a Heal or Buff Removal
Remember: to place any effect on an enemy champion, you will need to ensure your champion has enough accuracy to beat the opponents Resistance value. Likewise if you want to resist an enemy effect you need to have enough resistance. You can use our Raid Stages Tool (free account required) to view every opponents stats and make a decision on how much Accuracy or Resistance you need.
Understanding each effect will be vital in building your champions correctly and also which champions are better suited for each encounter. Below is a complete list of the effects you will face in the game.
All buffs applied to the champion with this Debuff active are automatically blocked and have no effect.
Block Active skills:
Prevents the champion with this Debuff from using their active skills (only when this Debuff is active). The champion can only use their default or passive skills for the duration of the Debuff.
Block Passive skills:
Prevents the champion with this Debuff from using their passive skills (only when this Debuff is active). The champion can only use their default or active skills for the duration of the Debuff.
Any healing received by the champion with this Debuff active is reduced between 50% or 100% depending on the champion’s skill description.
Block revive is an effect that prevents an enemy from being revived by their allies. This is particularly strong against the Ice Golem Dungeon where the boss is able to revive his fallen allies and in the Arena where often we face a team with champions that can revive their allies.
When this Debuff is placed it is seen as a countdown when this Debuff expires the affected champion suffers direct damage that ignores their DEF value. The damage inflicted by the bomb scales in accordance with the Stat indicated within the champion’s skill description.
Decrease ACC (Accuracy):
When this Debuff is applied, it reduces the champion’s battle accuracy by 25 to 50% dependant on the champion used to apply. This is in accordance with the champion’s skill description.
Decrease ATK (Attack):
When this Debuff is applied, it reduces the champion’s battle ATK by 25 to 50%. (dependant on the champion used to apply). This is in accordance with the champion’s skill description.
Decrease DEF (Defence):
When this Debuff is applied, it reduces the champion’s battle DEF by 30 to 60% (dependant on the champion used to apply). This is in accordance with the champion’s skill description.
Decrease SPD (Speed):
When this Debuff is applied, it reduces the champion’s battle total speed by 15 to 30% (dependant on the champion used to apply). This is in accordance with the champion’s skill description.
When this Debuff is applied, the affected champion(s) will be unable to move until the Debuff expires. Champions receive 75% of Normal damage whilst under this Debuff. Cooldowns do not refresh whilst the affected champion(s) is under this Debuff.
While the Debuff is active, at the start of the affected champions turn, they and all their allies take damage equal to 3% of their respective MAX HP. There can only be one HP burn Debuff active on one champion at a time.
This is a special debuff in that it doesn’t have impact on the champion with the debuff until another champion interacts with it. The impact of Hex champions is normally significant and can lead to powerful damage.
Any champion that attacks a champion with this Debuff active heals for 18% of inflicted damage.
Damages the target champions by 2.5/5% of their MAX HP at the beginning of their turn. Damage scales in accordance with the target champion’s MAX HP. Buffs like block damage will ignore the incoming damage. If a shield is active on the target champion the Poison will be applied to the shield first.
When this Debuff is applied, Poison damage taken by the recipient is increased by 25%/50% depending on the champion used to apply this Debuff.
The champion with this Debuff can only attack the champion that applied the Debuff for the indicated amount of turns under the champion’s skill description. ONLY the default skill will be used throughout the duration.
The champion with this Debuff applied is unable to act/ take their turn until the Debuff expires. Cooldowns are not refreshed while sleep is active. If a champion is attacked whilst asleep, that attack WILL wake them up and their Turn Meter will continue as if they had never been asleep.
The champion with this Debuff is unable to act/ take their turn until the Debuff expires. Cooldowns are not refreshed whilst this Debuff is active.
When this Debuff is applied, the champion that this has been applied to receives increased damage by 15/25% depending on the skill description of the champion who applied the Debuff.
Fear / True Fear:
When the Fear Debuff is applied, the enemy champion will have a 50% chance on their turn to skip their turn without their ability activating.
True Fear is an enhanced version of Fear, when an enemy with True Fear attempts to use a skill there is a 50% chance of the skill not activating, and if successful that skill will also go on cooldown!
Decrease C.DMG (Critical Damage)
When Decrease C.DMG is applied, the opposing champion being attacked will have their critical damage reduced by either 15% or 25% depending on the champion used to cast the Debuff. This effect is multiplicative (i.e. 200% Critical Damage will be 150% when debuffed by 25% debuff)
Decrease C.RATE (Critical Rate)
When Decrease C.RATE is applied, the opposing champion being attacked will have their critical rate reduced by either 15% or 30% depending on the champion used to cast the Debuff. This effect is additive (i.e. 70% Critical Rate becomes 40% when debuffed with 30% debuff)
When placed, removes all buffs from the target Champion and blocks any other buffs from being applied while the debuff is active. Enemies under petrification will skip their turn and their skills cooldown will remain the same whilst the debuff is active. Additionally, damage is reduced by 60% for petrified enemies except for damage dealt by Bombs which are increased by 300%.
There are a number of unique effects that a boss will place. Below we list them in one location but check our guides on each boss to learn more about the encounters.
Life Barrier – Hydra Head
When placed, Life Barrier creates a Shield on the target for a number of turns. This Barrier will receive incoming damage before any other shield effect or the target’s HP. If the Barrier is depleted the target is stunned for 1 turn. If the Barrier is not depleted, the target is fully healed.
Poison Cloud – Hydra Head
When placed, Poison Cloud blocks all damage from Poison Debuffs and converts all incoming attacks to weak hits. If the target of the buff is under the effects of HP Burn, then both effects are neutralised.
Vengeance – Hydra Head
When placed, increases the target’s damage by 300% for 1 turn and triggers an immediate AoE attack.
Serpent’s Will – Hydra Head
When a new Hydra Head is grown, this head will receive this buff reducing all incoming damage by 75%
Digesting – Hydra Head
This hydra head has recently devoured an enemy champion. The head receives additional HP. If the head is not defeated by the time this buff expires then the devoured champion is removed from the battle (cannot be revived or returned to your team). If the head is defeated, the champion is returned to your team.
Pain Link – Hydra Head
Target’s an enemy champion creating a link with the Hydra Head of Suffering. 15% of the damage received by the Head is taken as damage by the target champion.
Mark of the Hydra – Hydra Head
Marks a champion for devouring. After the counter is reduced to 0 the champion is devoured by a head and the head receives the Digesting Buff. Champions who are devoured are no longer part of your team, cannot attack or take turns.
