What Block Active Skills does in raid
How the Block Active Skills Debuff Works
Block Active Skills is a control debuff that prevents enemies from using their active abilities, forcing them to rely on their default A1 attacks or passives while the debuff remains active. This can significantly reduce the threat posed by enemies that rely on powerful damage, support, cleansing, or control skills, allowing your team to manage encounters more safely.
One of the key advantages of this debuff is that it can be Debuff Spread, and the duration can be extended through Debuff Extension, allowing enemies to remain locked out of their important abilities for even longer. It is also particularly effective against Mythical Champions in PvP, as a champion affected by Block Active Skills cannot use the skill required to switch forms, preventing them from accessing their alternate kit and limiting their impact.
Why Block Active Skills Is Strong
It’s a powerful debuff because it allows you to shut down many of the most dangerous abilities enemies rely on, forcing them to use only their default attacks. This can prevent healing, cleansing, buffing, crowd control, and high damage abilities from being used, making fights much easier to manage.
Why Block Active Skills champions are valuable
Block Active Skills is strong because it shuts enemies out of the abilities that usually make them dangerous, while still letting your team continue the fight in a more controlled manner. In wave based content, it can stop enemies from using their strongest attacks, revives, heals, cleanses, buffs, or crowd control skills, making difficult waves much easier to handle before they spiral out of control.
It is also valuable because the debuff can be extended, allowing you to keep enemies locked to their basic attacks for longer than many other control effects. Against Chimera, it has extra value for countering the Viper form, where preventing key active skills can reduce the threat of the phase and make the fight far more manageable.
Best areas to use Block Active Skills champions
PVE Waves
Block Active Skills can be extremely effective in content like Grim Forest, Cursed City, Doom Tower, and difficult dungeon waves because it prevents enemies from using the abilities that often make stages challenging, such as revives, cleanses, crowd control, or powerful attacks. This becomes even more valuable in stages with champion restrictions or special conditions, where controlling dangerous enemies can often be more reliable than trying to overpower them through damage alone.
Arena
It can be very powerful in PvP because it prevents enemies from using the abilities their teams are built around, forcing them to rely solely on their default attacks. This can shut down key champions before they have a chance to influence the fight. It is also one of the most effective counters to Mythical Champions, as they cannot use the skill required to switch forms while under Block Active Skills, preventing them from accessing their alternate kit and significantly reducing their impact on the battle.
Faction Wars
This debuff can be very helpful in Faction Wars because it allows teams to control dangerous enemies and prevent them from using the abilities that often cause runs to fail. By limiting enemies to their basic attacks, your team takes less pressure from revives, crowd control, and high impact skills, making stages much safer to manage. This added control can be especially valuable when aiming for 3 star clears, helping keep all allies alive while progressing through difficult stages.
Viper Form – Chimera
Block Active Skills can be particularly useful against the Viper form in Chimera, as it prevents the boss from using its active abilities and forces it to rely on basic attacks instead. This can significantly reduce the threat posed during the phase, making it easier for your team to manage incoming mechanics, maintain control of the fight, and focus on dealing damage safely.

Here we’ve highlighted some of the top Block Active Skills champions in Raid: Shadow Legends, showcasing the different strengths they bring. While this list isn’t exhaustive, it should give you an understanding of what makes these champions so effective. For more options, be sure to check out our Champion Tier List.
Lugan
Lugan has become a much stronger Champion following his buffs, now able to place Increase DEF, Ally Protection, and Shields on all allies through a single skill. Combined with his ability to place Block Active Skills, decrease enemy buff durations, and contribute respectable damage, he stands as a strong hybrid support option for waves and boss encounters. He can also counterattack whenever allies under a Shield are attacked, creating additional opportunities to trigger his Stun A1. To round out his kit, his damage increases based on the number of buffs he has placed on allies.
Basim
While protected by veil type buffs, his A2 not only ignores 30% of an enemy’s DEF, but also allows his Block Active Skills debuff to bypass Block Debuffs, making it far more difficult for opponents to counter. Beyond this, Basim is a solid damage dealer in both AoE and single target scenarios. His A3 increases in damage by 5% for each buff and debuff on both himself and the target, stacking up to 100%, allowing him to scale into a stronger damage dealer as battles progress, and when properly set up
Jingwon
Following his multiple buffs over the years, Jingwon has become a solid all round Champion. His A2 places both Block Active Skills and Block Buffs, making him effective for controlling enemy skills while shutting down enemy buffs. He can also increase the duration of all debuffs on enemies, helping your team maintain key effects for longer. His A3 removes buffs from enemies while placing Decrease ACC and Decrease C.DMG, alongside Strengthen for allies, providing a strong blend of support and survivability.
Ethlen
Ethlen strikes a strong balance between damage and control. His A3 places Increase C.DMG and Increase ACC on himself before granting an Extra Turn. He can then attack all enemies twice, placing Block Active Skills on targets or True Fear on those not under the debuff, giving him strong crowd control potential. Alongside this, Ethlen passively ignores 10% DEF when attacking Support, DEF, and HP Champions, helping him deal more meaningful damage against tankier opponents.
Karnage
In his base form, Karnage attacks a single target three times, placing Block Passive Skills on the first hit, Block Active Skills on the second, and stealing Turn Meter on the third. His passive then gives him a 50% chance to spread a random debuff to all enemies with each hit, increasing to 100% whenever he kills a target. Beyond this, Karnage is also a powerful buff steal & HP swap Champion who can transform into an alternate form focused on dealing heavy AoE damage.
Vlad
Through Vlad’s A3, he places both Decrease DEF and Block Active Skills on all enemies while placing Perfect Veil on himself. This provides a strong combination of offensive support and control for waves, while also contributing respectable AoE damage. He further supports the team through his A2, which places Leech and steals a portion of Turn Meter from enemies.
His passive adds another layer of value, triggering a self- heal and Turn Meter boost whenever he defeats an enemy, while also granting Revive on Death for additional survivability. This blend of damage, control, and self sustain makes Vlad a strong hybrid option for wave content & PVP progression.
Kroz
Kroz excels against multiple enemies, making him solid option for content like Faction Wars waves and PvP progression. His A2 places two Bombs on enemies and fills his Turn Meter by 25% for each enemy affected, allowing him to quickly cycle into his follow up abilities. His A3 then decreases Bomb detonation cooldowns while placing Block Active Skills on enemies, combining damage and control in a single attack. To round out his kit, he passively fills ally Turn Meters whenever Bombs detonate, helping your team maintain momentum throughout the battle.
Galathir
Starsage excels as a versatile support Champion, covering multiple roles for your team. His crowd control comes primarily from his Alternate Form, where Dark Nebula [A3] increases ally Accuracy while placing Decrease RES and Stun on all enemies. Combined with his A2 buff removal and Block Active Skills, he becomes a powerful option for disrupting enemy teams.
He can also reduce enemy Turn Meter, while his passive increases his own Accuracy and reflects crowd control effects back at enemies with higher ACC. In his base form, Starsage focuses on protection, providing Perfect Veil to revived allies, cleansing debuffs, placing Block Debuffs, and preventing his own death while equalising team HP when needed.
Bellower
Although the chances aren’t the highest, Bellower is a Void Rare Champions capable of placing AoE Block Active Skills through his A1, with a 30% chance. With enough turns, this can create surprisingly effective lockout potential, especially when paired with sets such as Stun for additional crowd control. He also brings two additional AoE skills, one placing Decrease SPD and the other applying Decrease ATK and Decrease DEF. The Nature’s Bounty blessing can further enhance these debuffs, giving Bellower even more utility for wave based content.
Yukimasa
Yukimasa’s A1 functions similarly to Bellower’s, but with a higher 40% chance to place Block Active Skills. Better yet, the debuff cannot be resisted against enemies already under at least one control effect, making him a solid lockout Champion when paired with crowd control allies, or set up from his A2.
He also brings the ability to ignore Block Damage with his A2, place Freeze on enemies, and revives one ally when he fails to secure a kill – or revives the entire team if he does. To round out his kit, his A3 steals Turn Meter from a single target, with the damage increasing based on the amount stolen, giving him a strong blend of control, utility, and damage.
Ramantu
Ramantu has a unique approach to applying Block Active Skills. Before attacking with his A3, he removes all buffs from enemies, then places Block Active Skills on those without passives, or Block Passive Skills on those who have them. While being able to apply both effects simultaneously would be incredible, each debuff provides powerful control in its own right and can shut down key enemy mechanics.
He also brings a four hit attack capable of placing several valuable debuffs, making him effective even against bosses. To round out his A2, he can then place True Fear on enemies if the target is under four or more debuffs, giving him additional crowd control synergy.
Lydia
If you’re looking for a Champion that blends control and support, Lydia is an excellent option. While she doesn’t provide AoE Block Active Skills, she can lock down key targets with the debuff, making her particularly effective against threats such as the Chimera’s Viper Form. She also brings Block Buffs, AoE Decrease DEF and Weaken, giving your team powerful offensive support.
Beyond her debuffs, Lydia provides Strengthen and Increase SPD for allies, denies enemy revive attempts, and can revive all fallen allies if she remains alive. This combination of support, control, and utility makes her one of the most versatile Champions in the game.
Komidus
In his base form, Komidus can steal 100% of a target’s Turn Meter while placing their skills on cooldown, while his A2 removes all buffs from enemies before placing Block Active Skills and stealing 20% Turn Meter for each enemy affected. This creates a powerful cycle of disruption that allows him to take turns more frequently while leaving enemies vulnerable.
After metamorphing into his Alternate Form, Komidus shifts into a Bomb specialist capable of instantly detonating Bombs on enemies under Stoneskin or those with lower current HP than himself. Enemies who have their Bombs detonated by this skill are also Stunned, adding a layer of crowd control on top of the damage. He combines this with AoE Weaken, self healing, Extra Turn potential, and additional Bomb placement through his A1, making him a dangerous blend of control, self sustain, and damage.
How to build Block Active Skills Champions
Accuracy & Speed Requirements
Accuracy and Speed are both important for landing Block Active Skills consistently. Accuracy is needed to pass the Accuracy vs Resistance check, ensuring your debuffs actually applies after the skill is used, while Speed allows your champion to take turns more often and apply Block Active Skills before enemies get a chance to act. As a general guideline, aim for around 25 Accuracy higher than the enemy’s Resistance, and use tools like the Raid Stages Tool to check specific requirements for each area.
Buffs like Increase ACC and debuffs like Decrease Resistance can further improve your consistency, especially when progressing through content where reaching higher stat thresholds is more difficult.
Recommended Artifact Sets
Block Active Skills champions benefit most from artifact sets that improve their Accuracy & Speed, ensuring they can land and maintain their debuffs consistently. Gear sets that provide Accuracy, such as Perception or Feral, are great for helping you reliably apply the effect while also boosting useful stats like Speed. Depending on your champion’s cooldowns, sets like Relentless, Impulse or Reflex can be effective for cycling back to your control skills faster and keeping enemies locked down.
Ideally, you’ll be using a champion who can apply these debuffs frequently, so once your Accuracy requirements are met, you can shift focus toward survivability or damage, depending on their role. For more hybrid, damage focused crowd control champions like Vlad, sets like Stoneskin for PVP, Savage, Merciless, or Lethal can be strong options, combined with Accuracy banners, substats, and 2 piece sets like Perception to maintain enough Accuracy while also increasing overall damage output.
Tips for using Block Active Skills Champions
Block Active Skills Champions are at their best when used to shut down high priority enemies before they can use their most dangerous abilities. In Arena and wave content, landing the debuff on key supports, revivers, Mythicals, damage dealers or crowd control Champions can completely disrupt the enemy team’s strategy and create openings for your damage dealers to take over the fight.
To get the most value from these Champions, prioritise enough Accuracy to land the debuff consistently, alongside sufficient Speed to act before the enemy. Many Block Active Skills Champions also bring additional utility such as Block Buffs, Turn Meter manipulation, buff removal, or damage, so look to build teams that take advantage of their full kit rather than relying on the debuff alone.
