Kalvalax Review

Kalvalax is a Legendary Attack Spirit affinity champion from Knights Revenant faction in Raid Shadow Legends. Kalvalax was released in Patch 4.60 in September 2021. The champion design of Kalvalax was created by David Fitzsimmons, who won the Community Champion Concept contest in 2021!

Kalvalax’s kit is heavily focused on inflicting poisons and increasing his damage from them. He has a passive that is incredibly strong in all areas of the game, allowing him to start with 4 poisons, which is perfect for a poison explosion team or Clan Boss. He’ll also place another poison for 1 turn with a 50% chance. His A1 skill will extend these poisons with a good chance, which means he can place and sustain a substantial amount of poisons on a single target, making him an ideal candidate for Clan Boss.

Kalvalax’s A2 and A3 skills are devastatingly powerful. The A2 skill has the potential to hit four times, while his A3 skill is similar to that of Dracomorph and Lord Shazar, where he can boost his damage based on the number of debuffs on the target. With the right team, his A3 can become a complete nuke!

Overall, Kalvalax is a powerful poisoner with high damage potential and great versatility in all areas of the game. Whether it’s for Clan Boss, Dungeons, or Arena, he can be a game-changer for your team.

Kalvalax Storyline

Once, a long, long time ago, in the lands of Kaerok that yet knew no king, there lived a great warrior by the name of Kalvalax. He was no scion of an ancient bloodline, but it was an age where one’s nobility was measured less by a long list of eminent ancestors and more by the number of warriors under their banner. Of those, Kalvalax had no shortage. Blessed with strength and cunning alike, he knew no equal on the field of battle and led countless campaigns against the Orc tribes that populated the plains of Arnoc. He razed their crude settlements and put anyone who dared resist him to the sword. Within a decade, a vast swathe of land had been liberated from savages, and the budding city bestowed a Duke’s diadem upon Kalvalax, to whom they owed their newfound prosperity. Thus his rule begun: in blood and fire and ruthless conquest. Many a bold challenger sought to take the Duchy from Kalvalax only to find untimely death, while his fame – or infamy – grew. And the more foes perished by Kalvalax’s blade, the more convinced he became of his immortality. But hubris is often deadlier than even the cruelest of monsters.

Doom did not take the shape of an invading army or a raging dragon – it was a disease that many sages maintain was divine punishment for Kalvalax’s arrogance, or an ancient curse he had unwittingly invoked. The plague swept Arnoc like a tidal wave. Even Kalvalax himself could not escape the unseen miasma of decay. He fell ill and weakened by the day, unable to fight this unseen enemy as he had fought those who challenged his rule. Desperate, he prayed for salvation and vowed to pay any price, no matter how steep. And a dark, ancient force heard his prayers. A stranger arrived to Arnoc that fortnight – an old man wrapped in black robes and shadow. He walked the streets, unafraid of the plague, and arrived at Kalvalax’s castle to offer a solution to the doom that threatened the city. All he asked in return was the Duke’s willing cooperation and a sacrifice of innocent blood. By then, the citizens of Arnoc were as desperate as their ruler and eagerly followed the prophet’s instructions. Dozens were brought to the altar like sheep and slain, while Kalvalax, clad in armor with full regalia, bore witness.

Then, as the sacrificial chalice overflowed with blood, ripples of arcane power tore through the city. Chronicles describe clouds of plague mist being swept by hurricane wind and carried towards the castle, where the mad prophet channeled them into Kalvalax’s body and sealed all of the city’s woes within. What became of the Duke next, none can say. Some say he perished that day. Others maintain that it was all a ploy by the cult of K’leth – the Knights Revenant – and Kalvalax had fallen into their thrall. One thing is certain, the legend of a nightmare knight, clad in ancient armor that oozes with pestilence, emerged soon after, and very few are those who witnessed that walking horror and lived to tell the tale…

    @Michael Tunudd: Seems that I missed out updating the champion list in the Doom Tower Floors page. Thanks for highlighting it!

  2. Treert

    Sry about the inappropriate profile picture. someone hacked into my account apparently. I changed it but the old one is still showing up.. probably in my cookies

  3. Treert

    @mother of dragons. I keep them up the whole fight about 75% of the time with relentless and high speed. Unbooked

  4. Dargentina

    Worth mentioning (if it hasn’t been), this bastard can go first than Hegemon.

  5. MotherOfDragons

    @Just Pepe, may I ask what gear you have Kava in where he’s able to keep all those poisons up? Just curious. I want to try the way you described. I threw more books at him, 1 short of the max on his A1. So I’ll keep trying.

  6. Just Pepe


    I’ve noticed the passive only fails to always “work” when a lot of poisons happen at once. Like in Dragon or Agreth. Maybe it has something to do with the how many times the cleanse/buff has to occur causing problems, or in cases the c heals might go over the 10 buff limit?

    Also, I use him in my CB Easy Maneater unkillable. In my team, I have the Fat with the ally attack and poisons and Aothor for more poisons. With Kalvalax’s A1 fully booked, I usually get more than 1 a1 attack from him factoring in counter attacks and ally attacks. I turned off Kalva’s a2 but kept that big hit a3 in the rotation. With that setup he usually keeps about 4-10 poisons going for each round. If the RNG gods are a-holes, there is the rare occasion the CB takes a turn with 0 poisons. He’s averaging about 10M per run, but I have so-so gear. But he’s increasing the poison value of Aothor and the Fat, so he’s debuff extending support and poisoner and damage all together. But his poison extension is by description not a dependable role for him to be in without maximizing times he uses his a1.

  7. MotherOfDragons3

    @bad bed bug, thanks for the clarification. Yes, buffed is what I intended. If you have to turn off his A2 & A3, that makes him completely pointless to use, as it’s too difficult to keep up with. What a waste. My other issue with him, is him taking poison damage when he isn’t supposed to. He will throw up the Contin Heal, but will also take poison damage such as in Spider & FK. He also does not “instantly remove them, like stated. He will keep them for 2 turns and collect the damage. This needs attention. I’ve sent in requests, but never heard back.

  8. bad bed bug

    @peacefuldavid, @MotherOfDragons3
    to make him keep the poisons up you need to turn off his A2 and A3, so he uses only A1 and extends the poisons duration. However this way you are at risk of losing other debuffs like dec at or dec def if Kalvalax extends debuffs continuously, especially if you give him Sniper and Master Hexer masteries.

    Obviously even with only A1 turned on he can lose poisons, but wbetween all the extenders only Ovelis is a really trustful one.

    @MotherOfDragons3, accuracy 145 is enough only for normal CB… for Nighmare he should have at least 200 for Ultra – 220+ (And by the way, nerf is actually when the extremely great champion is getting worse, so you’d wish Kalvalax buffed instead 😉 )

  9. Michael Tunudd

    Hi, my name is Michel Tunudd (Sweden).
    Just want to point Your attention to a mishap(?) regarding Kalvalax.
    On this page he is given 5* at Doom Tower, Floors BUT in the List on Doom Tower Guide he is among the 4*.
    4★ Floors | Legendary Champion
    Baron (BL-LAV)
    Belanor (HE-LAV)
    Brakus the Shifter (SW-LAF)
    Cillian the Lucky (BL-LAM)
    Drexthar Bloodtwin (DS-LDF)
    Drokgul the Gaunt (OT-LSS)
    Elder Skarg (BA-LAF)
    Elenaril (HE-LAM)
    Harvest Jack (UH-LHS)
    Iron Brago (OR-LDS)
    Jintoro (SK-LAM)
    Kalvalax (KR-LAS)

  10. MotherOfDragons3

    @peacefuldavid, I am feeling the same way. I built him like a tank, and his Crit damage is 147, and ACC is 145, CR 125, and his speed 187, no matter what I do, he fails to keep the poisons up, after the initial ones placed before turns have started. He can land them, but they don’t stay and so this has severely influenced his gameplay, and I end up using someone else. He just is not consistent and needs some nerfing.

  11. peacefuldavid

    This champion is a massive disappointment. I built him for clanboss – and he is unable (even with high acc) to keep the poisons up. After the initial 4, he can’t keep them up. I am running at 191 speed on UNM – but the poisons fall off none-the-less with 1:1 speed. He is even worse on Ice Golem. Again, initial poisions are impressive — but they don’t stay up and are never reapplied. His hits aren’t particularly hard either.

  12. Ralf

    Wäre es nicht eine gute Idee Kalvalax mit Gift-Artefakten auszustatten um seine “natürliche Kraft” noch zu stärken?

  13. Killjoy

    Curious why one would take Opportunist Mastery on Kal? He does not place any of the debuffs it increases the damage on. Am I misunderstanding the mechanics of the mastery? Or would Cycle of Violence be a better pick at that mastery level?

  14. Stephan

    Am i blind or is there no masteries for this champ ?

  15. Toshi

    sorry I saw them

  16. Toshi

    still no mastery ?

  17. Zheph

    @Robegs It seems due to his passive having a 1 turn cooldown, he can only remove 1 poison before he needs to take another turn to reset its cooldown. I think a lot of YouTubers overlooked this. I had ideas for him in Spider as the tank with Opardin’s passive to get a lot of turn meter from all the continuous heals, but he doesn’t work out that way.

  18. Enrico

    I can’t imagine him pairing up with Zavia and Bad-El Kazar anywhere, now that I have him in my possession. It’s going to be so much fun.

  19. Robegs

    Why is he getting poisons from the nether spider? The passive says he “removes” the poisons, and the nether spider places poisons that cannot be resisted or blocked, but they can be removed.

  20. Justin Baylord

    I would love to pair him with Zavia and make a poison explosion arena build.

  21. sin

    @mike: he’s not known for his hits, his hits are just a bit above average. he’s primarily used for his poisons. put him along with frozen banshee or other ‘poison sensitivity’ champs and you’ll see what he can do. or in dungeons or tower put him with zavia or Elanaril and he will wipe the waves.
    his a3, can hit as hard, maybe even harder, as septimus, if the enemy is under 10 poison.
    his a2, I believe, does not proc giant slayer.
    alone, he is an OK champion, but for him to be meta, you need other champions.

  22. Mike

    What is wrong with him, not the 1st to discuss this any thoughts? I built him for unkillable clan boss he has currently Power Level 60,500 Key stats 5500 Att, 106 Crit rate 220 Crit Damage and 236 Acc – He hit like a wet noodle! Kalval – Laxitive more like it! His 4 hitter gets like 40k per hit, his other gets 45-60 k hit, my maneaters do that Fayne hits harder. When the comp ends Fayne 20 million Kal half at 10M Maneaters 8.5 mil
    What does he need to do, what should I change should I push attack and get rid of the ACC?
    Very disappointed all the books and money spen he should hit like Jintoro. This was supposed to be a flag ship character not seeing him used anywhere.

  23. Ayumilove Post author

    @Laerervad: There are 2 ways of building Kalvalax, which is full offense (Attack, Critical Rate and Critical Damage) or as a debuffer champion mainly to place Poison and have high amount of survivability by equipping HP% and Defense equipments. The full offense route is a good choice if you have sufficient stats to make him tanky enough to survive the enemy attacks. Otherwise, having him with high survivability allows him to bring more damage with his Poison in a long battle, especially traditional Clan Boss team.

  24. Laerervad

    Isn’t he supposed to be build with a ton load of attack and crit, instead of def and HP?

  25. Aute

    Looking at his skills, his usability should perhaps should be shifted to mid-late game and rank upped to A.

    While not being particularly useful at early game, the skillset is unique and very strong vs CB or late pin cushion enemy groups.

  26. Ayumilove Post author

    @Flob: I have included Kalvalax Speed Aura. Thanks for highlighting the missing skill!

  27. Flob

    Doesn’t this guy have a speed aura? It’s not shown here.

  28. Ayumilove Post author

    @drm31415, @Synn7645: I have corrected Kalvalax’s A1 skill upgrade description. Thanks!

  29. drm31415

    Like Synn7645 said, on A1
    Level 3: Buff/Debuff Chance +10%
    should be
    Level 5: Buff/Debuff Chance +10%

  30. Jeff

    it seems not good as Dracomorph

  31. Megalodon

    I think you have him underrated also. I am a late game player and he has found his way onto two of my dungeon team improving the speed farming with poison explosion teams. I guess time will tell his overall utility as more people pull this champ.

  32. Koalabacon

    Underrated. He can be a top tier wave clearer in the right setup. He also has huge potential as a low resist spider tank or part of a poison explosion team.

  33. Synn7645

    There’s a small typo, underneath Kalv’s A1 you have the upgrade listing as: 2, 3, 4, 3. Thank you for all of the work you do, Ayumi!
