Big ‘Un Review

Big ‘Un is a Legendary Attack Magic affinity champion from Ogryn Tribes faction in RAID: Shadow Legends. Big ‘Un is one of the top damage nuking champions in the game! All of Big ‘Un attacks are AoE (Area of Effect), which makes him viable in many areas such as Nightmare Campaign speed farming, Arena Blender Teams and crowd controlling mobs in dungeons, Faction Wars and Doom Tower with his Stuns and Decrease Turn Meter.

To unleash Big ‘Un’s full nuking potential, it’s best to equip him in Savage Set paired with Helmsmasher mastery and supported by a debuffer champion who has Decrease Defense and Weaken debuff skill! In addition, Big Un has an Accuracy Aura in All Battles, which is useful for early game players. The aura provides an ample amount of Accuracy stats to enable his team members to successfully apply debuff on enemies (e.g. Poison Debuff, Decrease Defense, Weaken, Stun, Decrease Turn Meter) as it will be difficult in early stages to farm decent Accuracy Banner from Spider’s Den or Accuracy chestplate from Dungeons!

Big ‘Un Reference

Big ‘Un Damage Build

The artifacts equipped on Big ‘Un are optimised for Arena, Faction Wars and Doom Tower content. Savage Set is used to ignore enemy defense and utilizes Helmsmasher (Tier 6 Offense Mastery) to ignore up to 50% enemy defense. Big ‘Un can ignore 100% ignore defense when he is paired with a debuffer champion who has the ability to inflict 60% Decrease Defense debuff on the enemy before Big ‘Un strikes them down. This allows Big ‘Un to bypass enemies defense and quickly knocking them out of battle. Big ‘Un is equipped with an Accuracy Banner to provide him with decent amount of Accuracy, so that he could apply his Decrease Turn Meter, Stun and Decrease Speed debuff on enemies for PvE content (e.g. Campaign, Dungeon, Faction Wars).

    In his Crit dmg vs ignore def video he uses Big `Un as an example

  2. Yolo

    Doesn’t Ash say Crit dmg gear and mastery is better in arena than Armor Pen?

    @jack: Yes, you could run Big ‘Un in Stun Set if you are using him to crowd control enemies in Arena and Dungeon waves if your team is not able to knock out the enemies within the single turn with Big Un AoE attacks!

  4. Ayumilove Post author

    @MrBoop: Yes, Big ‘Un “Molten Slag” (A3 Skill) decreases the enemies turn meter for every hit if successfull. However, you need to have a decent amount of Accuracy for high level content such as Dungeon Stage 20~25 (approximately 225~250 Accuracy for dungeon content).

  5. MrBoop

    Does each hit in his A3 decrease turn meter/has a chance to place the debuff?

  6. jack

    could you not run a stun set with high accuracy, crit rate, damage and speed for nuke arena and dungeon waves?

  7. Bacon knight

    Got 3 Big ‘Un mmaayybee 6 star the last 2 for some fun to use with an ally attack or ca combo!!

    @Karamnik: You can use Swift Parry Set on Big’Un to avoid getting 1 hit KO by enemies in Arena.

  9. Ayumilove Post author

    @DoctorWhoLaLa: Big’Un can greatly benefit from Retribution, where he counter-attacks the enemy when they hit him hard. This is especially useful in Arena too! Defense Mastery provide him some survivability because Big Un is pretty squishy if you build him with full attack stats.

  10. Karamnik

    Hi, what about a swift parry set for this champ?

  11. luckmonkey

    Bigun is 5 star for all dungeons simply because of how well he handles the waves. Plus has a little TM reduc on several bosses

  12. DoctorWhoLaLa

    Hi! I appreciate you making this guide, has been a big help! Was wondering why you would choose to have defense masteries for Big Un rather than support? Thank you 🙂

  13. Aeolwind


    Yes, he has 2 multi-hit skills and he has turn meter manipulation along with slow speed. He is good on the waves leading in, even if he has negative affinity on FK20.

  14. GoTo

    Big un is 5* for FK?

  15. Sven

    How come not the support tree? to increase his ACC
