Best Block Buffs Champions for Hydra in Raid Shadow Legends
In this guide, we’ll explore the importance of Block Buffs for Hydra in RAID: Shadow Legends. We’ll explain how the debuff works, why it’s considered one of the most valuable effects for Hydra teams, and how it helps counter key Head mechanics by preventing dangerous buffs from ever being placed.
How Block Buffs works in raid
Block Buffs Explained
Block Buffs is a debuff that prevents enemies from receiving new buffs while it is active. Any buffs an enemy already has will remain in place until they expire or are removed, but they will be unable to gain additional buffs from skills, passives, or other effects for the duration of the debuff. This makes Block Buffs a powerful debuff for preventing enemies from gaining effects that could improve their survivability, damage, or utility, and allowing your team to maintain control of the fight more easily.
Why Block Buffs Is Strong For Hydra
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.
Why Block Buffs champions are valuable for Hydra
Stop Hydra Heads From Placing Buffs
Block Buffs prevents heads from gaining their most disruptive buffs, allowing your team to deal with their mechanics much more effectively. Keeping Block Buffs active can stop heads from applying effects that increase their survivability or make them more difficult to damage, helping your team maintain control of the encounter. It is also useful against the Head of Mischief, as it prevents them from gaining stolen buffs from your team and spreading them to the other heads.
Understanding Hydra Mechanics
Multiple Hydra Heads
Taking on Hydra can feel overwhelming as you progress through the higher difficulties, with each of the six heads bringing unique mechanics that need to be managed. The Head of Torment can trap your team in True Fear cycles, the Head of Mischief steals and spreads buffs, the Head of Blight places Poison Cloud to force weak hits, the Head of Wrath gains Vengeance to unleash devastating attacks, the Head of Suffering protects heads through buffs and the passive, while the Head of Decay can cleanse key debuffs if left uncontrolled.
This is where Block Buffs becomes one of the most important debuffs for Hydra. By preventing heads from placing buffs in the first place, you can shut down dangerous mechanics such as Poison Cloud, and many of the protective effects that make Hydra harder to control. Combined with debuffs like Decrease SPD, Decrease DEF, Weaken, and Provoke, Block Buffs helps keep the fight manageable, allowing your team to maintain momentum and deal consistent damage as heads rotate and respawn throughout the battle.

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.
Firrol
Firrol brings one of the best Hydra kits in the game, combining Decrease ACC, Block Buffs, Increase RES, and Perfect Veil across his skills. This allows him to counter incoming debuffs, protect allies from the Head of Torment, and prevent Hydra Heads from placing their dangerous buffs. His passive further boosts ally RES and ACC by 50 when they have three or more buffs active, while also increasing damage dealt when they have four or more. This blend of protection, utility, and damage amplification makes him an outstanding Hydra specialist.
Venalicia
Not only is this Champion a strong reviver, but she also brings excellent utility for Hydra. She can remove buffs from enemies while placing Block Buffs and Decrease DEF, helping shut down key Hydra mechanics and increase your team’s damage output. She also applies Pain Link and Weaken. Venalicia’s revive returns allies with 50% HP and Turn Meter, increasing to 75% when reviving the entire team, while also reducing their skill cooldowns by 1 turn. This combination of revival, turn cycling, and reliable Block Buffs makes her an exceptional choice for Hydra.
Uugo
Uugo brings a simple yet highly effective kit for Hydra progression. Her A2 skill combines Decrease DEF and Block Buffs in a single ability, helping increase your damage while shutting down Hydra buffs. She also provides valuable sustain through an A3 that removes Heal Reduction and a random debuff before healing allies. In clutch situations, Uugo can even revive the team if she is the last Champion standing, giving her added safety and recovery potential. To round out her kit, her A1 places Leech, providing another source of healing.
Packmaster
Kro’khad is one of the best Legendary damage dealers for Hydra, and it’s here that the synergy with Packmaster truly shines. For Block Buffs, he can place the debuff without needing to hit enemies, allowing him to bypass affinity issues and reliably shut down Hydra buffs. He also boosts ally Turn Meters, buffs himself for potential Mischief tanking, and places Hex on enemies that attack him.
Esme
Not only is Esme a great source of Increase ACC and Increase SPD, but she also excels at removing buffs before following up with an AoE attack that places both Block Buffs and Weaken. This allows her to cover multiple key roles for a Hydra team in a single Champion slot. She also brings additional offensive support through her A1, which can place Increase ATK on allies, while her passive fills the Turn Meter of your highest ATK Champion whenever she is hit.
Belz
Belz is an often underrated Champion, but can be really effective in Hydra. He places Block Buffs and Leech on all enemies, then fills his Turn Meter based on the number of debuffs applied. His A2 skill can attack all enemies if his target is under Leech, while also stealing buffs from the initial target. His passive further boosts his effectiveness, increasing both his MAX HP and C.DMG by 5% per debuff placed, up to a max of 50%. This allows him to scale throughout the fight, turning his debuff utility into more damage potential.
Ostrox
Ostrox is about as straightforward as it gets, but that simplicity can still be valuable for progressing Hydra teams. He can place Block Buffs on all Hydra Heads for 3 turns, thanks to there always being four or more enemies present, as decapitated heads do not count as dead enemies. Alongside this, he provides Increase ACC for the team and a random debuff cleanse, helping your Champions land their effects while removing troublesome debuffs such as Provoke.
Masahiro
Masahiro is able to place both Block Buffs and Decrease SPD on bosses while simultaneously reviving all allies before the attack. Although the skill comes with a 4-turn cooldown, it combines two valuable debuffs with a powerful team recovery effect, making it especially useful in Hydra. He also brings the ability to transfer debuffs from allies onto an enemy, while healing the team and applying Strengthen for protection. His passive reduces damage taken by allies, and he rounds out his kit with an AoE A1 that places Decrease C.RATE, making him a strong candidate for sets such as Cursed if your team is lacking Hex.
Lamasu
Lamasu is a great Champion to consider for this role, thanks to her ability to place both Decrease SPD and Block Buffs against bosses with her A2. This alone provides excellent support, helping shut down enemy buffs while slowing their turn cycle. She also brings an A3 that cleanses a target ally, places Intercept to prevent crowd control, and resets their cooldowns, allowing key Champions to access their strongest abilities more often. To round out her kit, her AoE A1 places Decrease ATK, helping reduce the damage your team takes throughout the fight.
Othorion
Othorion is a powerful hybrid Champion who sets himself up with Increase ATK, Increase ACC, and Increase SPD before granting himself an Extra Turn into his core skill. His A2 is a double hit AoE attack that places both Block Buffs and Decrease ATK, while also filling his Turn Meter and dealing damage based on Enemy MAX HP. He further sustains throughout Hydra battles by increasing his MAX HP whenever he decapitates a Hydra Head, up to a cap of 50,000. Combined with an A1 that attacks all enemies.
Pheidi
Pheidi shares some similarities with Firrol, but brings his own unique strengths. He can place both Increase RES and Perfect Veil on allies while reducing their skill cooldowns by 3 turns, allowing your team to access powerful abilities more frequently while staying protected from Hydra mechanics. Alongside this, he can remove buffs from enemies, place both Block Buffs and Decrease SPD, and fill ally Turn Meters. This combination of protection, cooldown manipulation, and debuff control makes him an excellent support option for Hydra teams.
Thisbe
Thisbe fills a role similar to Uugo, but trades Decrease DEF for Hex alongside her Block Buffs. This makes her excellent for enabling Hex based damage while simultaneously shutting down key Hydra buffs. She also brings an A3 that decreases the duration of debuffs on allies, heals them, and fills their Turn Meters by 20%. To round out her kit, her passive causes allies to deal 10% more damage to enemies affected by her debuffs, making her a strong option for boosting both team utility and overall damage output.
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 significant 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 may find sets like 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 in Hydra
Block Buffs Champions are most effective when they take their turns before enemies can place key buffs, making Speed and consistent debuff uptime extremely important. In encounters like Hydra, keeping Block Buffs active can shut down dangerous mechanics such as Poison Cloud, and other effects, making the fight significantly easier to control. Pairing Block Buffs with buff removal can be especially effective, allowing you to remove existing buffs before preventing new ones from being applied.
When building Block Buffs Champions, prioritise enough Accuracy to land the debuff consistently, then focus on the stats that support their primary role, whether that’s damage, survivability, or team utility. Many of the best Block Buffs Champions bring additional effects such as Decrease SPD, Decrease DEF, Turn Meter manipulation, or team support, so make sure you’re taking full advantage of the rest of their kit rather than viewing them as a one debuff specialist.
