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…

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

  2. 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?

  3. Stephan

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

  4. Toshi

    sorry I saw them

  5. Toshi

    still no mastery ?

  6. 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.

  7. 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.

  8. 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.

  9. Justin Baylord

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

  10. 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.

  11. 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.

    @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.

  13. Laerervad

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

  14. 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.

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

  16. Flob

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

  17. Ayumilove Post author

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

  18. drm31415

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

  19. Jeff

    it seems not good as Dracomorph

  20. 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.

  21. 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.

  22. 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!
