Mighty Ukko Review

Mighty Ukko is a Legendary Support Force champion from the Skinwalkers faction in Raid Shadow Legends. Mighty Ukko was introduce in Patch 6.00 on September 2022 as part of the Champion Fragment fusion! His skill kit revolves around applying debuff on enemies, stealing their buffs, and buffing his allies. Apart from that, his abilities are mainly AoE attacks, which allows you to build him as a crowd-controller by equipping him in a Stun Set or Taunting Set.

Ukko Smash is his basic ability that attacks all enemies and has a chance to apply Decrease Attack, which is helpful in decreasing the enemy damage output so that they deal less damage to your team. To maximize the fullest potential of his AoE attack abilities, it’s recommended to gear Mighty Ukko in Taunt Set and Stun Set to allow you to prevent the enemy from using their active skills, especially at the higher difficulty of Dungeons, Faction War, and Doom Tower.

Ukko’s Fury is his renowned skill that strips away the buffs from the enemy and applies Block Buff and Decrease Accuracy. This is very useful in countering enemy team that relies heavily on buffs to improve their offensive and defensive capabilities! Even if the enemies were able to go first in battle to cast their buffs such as Nekhret the Great, Siphi the Lost Bride and Duchess Lilitu, Mighty Ukko is able to strip them away with ease provided you stack up sufficient Accuracy stats to prevent them from resisting it! Also, you will need to have him be quick to cut in the enemy’s sequence to erase those buffs before their attackers deal damage with the aid of those buffs. This skill is beneficial in helping you in end-game content, such as Hydra Clan Boss, Iron Twins Fortress, and Bommal the Dreadhorn too!

Ukko’s Mercy is his ultimate ability that revives all fallen allies and applies an Increase Speed buff on them, allowing Mighty Ukko to perform emergency rescue and keep your team surviving till the battle ends successfully. This is particularly useful for Faction Wars if you are attempting to get 3-Stars on each floor to unlock Lydia the Deathsiren as the ultimate reward!

Last but not least, his unique passive skill Totem Warden allows him to have a chance to steal the enemy’s buff. This is pretty handy for early-mid game players who are attempting to farm potions from the Spirit Keep and Magic Keep as the dungeon bosses utilize buffs such as large Shield and Block Debuff buffs on themselves. It can also be used in Arena to disrupt the enemy’s buff too.

Is Might Ukko worth going for during this Champion Fragment fusion? It’s a definite yes, especially for players who are lacking solid buff removers and debuffer (e.g. Madame Serris) and decent supporter hero who can revive allies (e.g. Duchess Lilitu). He will help you in one way or another regardless of your game progression (early-mid-late game).

  1. Shy of dropbears clan

    I agree that Stun set for PvP and anything with waves, but consider using Taunt aka Provoke set for the likes of Hydra (though seriously that might work for PVE / Waves also)

  2. Bryan

    Anyone that says Mighty Ukko is bad doesn’t know what they’re talking about. Yes I realize his block buffs is on a 4 turn cd which is a shame, but he is still bringing so much to the table and can excel in practically every area of the game.

    Also his block buffs ability was finally fixed and fully works on Hydra now. Which is great cause he’s fantastic for Hydra. An a1 aoe decrease attack, aoe double hit block buffs and decrease acc, and aoe revive with increase speed which he can still put up without having to revive, plus stealing buffs and protecting them with a nice speed aura? God damn, how can you say this dude isn’t good? He’s doing so much!

  3. sin

    I don’t get why people say it is a disappointment, it is an absolute nightmare in arena with it’s buff stealing, bloc buff and revive.

  4. Sydofnee

    Ukko in Stun set was the key for me finally completing Faction Wars 21 for Skinwalkers with Basher, Gnarlhorn, Hofrees and Reinbeast. Speed Aura and Revive from Ukko helped. Was 8:34 on Auto.

  5. JUN

    the mighty pig looks like an A tier, would be an S tier if any his skills was 3 turns cool down.

  6. Bos

    Horrible fusion, one of the worst for 4 turn cooldowns even for the non-revive skill. Utter rubbish to compare this to Helicath and clearly an insult to Brogni to even mention them in the same breathe as Ukko is asinine. I do not know what meds these Ccs are on, but they need their skulls checked again.

  7. Lola Blacks

    I think I might try relentless on this champ

  8. trevor

    This has been one of the most disappointing champs!

    He is so broken.
    His block Buffs work HORRIBLY in hydra.

    Doesn’t even work on Head of Poison and Wrath.

  9. HansVonMannschaft

    Is there a reason why absolutely no website, nor any CC in youtube are recommending neither Reflex nor Relentless? This dude has two skills on a 4-turn cooldown, what am I missing here?
