Best Block Buffs Champions in Raid Shadow Legends
Discover the importance of Block Buffs in Raid: Shadow Legends. Learn how this powerful debuff prevents enemies from placing buffs, why it is one of the most valuable effects for encounters such as Hydra, and how it can help shut down dangerous boss mechanics, waves, and PvP teams before they become a threat.
How Block Buffs works in raid
Block Buffs Explained
Block Buffs is a debuff that stops enemies from receiving new buffs while it remains active. Existing buffs are unaffected and will stay in place until they expire or are removed, but any attempts to gain additional buffs through skills, passives, or other effects will fail.
This makes Block Buffs one of the most effective debuffs for controlling encounters, preventing enemies from gaining protective, offensive, or utility based buffs that could otherwise swing the battle in their favour. By shutting down these effects before they can be applied, your team can maintain control more easily and deal with enemies before their mechanics become a problem.
Why Block Buffs champions are valuable
Block Buffs Champions are valuable because they can prevent enemies from gaining powerful buffs that often make encounters much harder to manage. Stopping effects such as Increase ATK, Increase DEF, Strengthen, Shields, Block Damage, Counterattack, or Reflect Damage can greatly reduce an enemy’s survivability, damage output, and overall value.
Rather than having to remove these buffs after they appear, Block Buffs prevents them from being placed in the first place. This allows your team to maintain control more easily, shut down dangerous effects, and make encounters far safer and more consistent to defeat.
Best Areas to use Block Buffs
Hydra Heads
It’s one of the most important debuffs in Hydra because many of the heads rely on buffs to become more dangerous, survive longer, or disrupt your team. By preventing new buffs from being applied, Block Buffs can stop effects such as Poison Cloud, Reflect Damage, Increase ATK, and other buffs that make the encounter much harder to manage. Maintaining consistent Block Buffs uptime allows your team to deal damage more effectively, avoid dangerous mechanics, and keep control of the fight, making it a core debuff for successful Hydra teams.
Countering Waves
Block Buffs is extremely effective in wave based content because many dangerous enemies rely on buffs to enable their mechanics. Preventing effects such as Increase ATK, Increase DEF, Shields, Counterattack, or Block Damage from being placed can make waves far easier to control and defeat.
By shutting down these buffs before they appear, your team can focus on controlling and defeating them without needing to spend turns removing protections afterward. This helps make wave progression faster and more consistent, especially in areas such as Doom Tower, Cursed City, and Faction Wars.
Arena Utility
It can be strong in PvP because it prevents enemies from gaining the buffs their strategy relies on, making them easier to control and defeat. This is especially effective against defensive and support heavy teams, as it limits their ability to protect allies, or set up stronger damage potential. By shutting down key buffs before they appear, Block Buffs can disrupt an opponent’s plan and create opportunities to secure wins.
Key Bosses
Block Buffs can be effective against a variety of bosses by preventing them from gaining buffs that make them more difficult. Outside of Hydra, it can also provide strong value in encounters such as Chimera, Dragon, and certain Grim Forest bosses by preventing effects like Increase ATK, Continuous Heals, or other buffs that increase pressure on your team. By stopping these mechanics before they occur, Block Buffs can make boss fights far easier.

How to build Block Buffs champions
Accuracy Requirements
Accuracy is the most important stat for Champions applying Block Buffs, unless the skill specifically states the debuff cannot be resisted. As a general guideline, aim for around 25 more ACC than your target’s RES to consistently land the debuff, using tools such as the Raid Stages Tool to identify the requirements for specific encounters.
Increase ACC buffs and Decrease RES debuffs can make reaching these thresholds much easier, particularly in higher end content like Hydra. Beyond Accuracy, your stat priorities will depend on the Champion’s role. Some Champions focus purely on maintaining Block Buffs, while others, such as Othorion, contribute damage or additional utility. In these cases, balancing ACC with Speed and the relevant offensive or defensive stats is key to getting the most value from their kit.
Recommended Artifact Sets
Gear sets that provide Accuracy, such as Perception, Pinpoint, or Feral, are excellent choices for Block Buffs Champions, helping them consistently land debuffs while also providing useful secondary stats like Speed. Depending on the Champion’s kit and cooldowns, sets like Relentless or Reflex can also be strong options, allowing them to cycle back to key skills faster and maintain higher uptime on Block Buffs throughout the fight.
Hybrid damage dealers such as Belz can benefit from pairing Savage, Merciless, or Lethal with Accuracy focused gear to balance damage output and debuff consistency. Champions who also provide valuable buffs or support may find sets like Mecurial & Protection particularly effective. Just be careful not to sacrifice too much Accuracy when moving into these more specialised builds, as consistently landing Block Buffs should remain the priority.
Tips for using Block Buffs champions
Block Buffs Champions are at their best when they can consistently prevent enemies from gaining key buffs, making Accuracy and Speed two of the most important stats to prioritise. Applying Block Buffs before enemies take their turns can shut down powerful defensive, offensive, and support effects before they ever become a problem.
Many Block Buffs Champions bring far more than just the debuff itself, often combining it with effects such as Decrease DEF, Weaken, buff removal, crowd control, or team support. Building teams that can keep these Champions alive and cycling turns efficiently will help maximise both their debuff uptime and overall impact, especially in buff heavy encounters where controlling enemy buffs is key.
