Realm of Carnage (Deadly) is an Advent Stage appearing on the 11th, 12th, 25th, and 26th of every month after clearing Into the Future chapter 1. When clearing the stage, there is a chance to unlock Express Cat. This is a No Continues stage. In The Battle Cats Unite!, it is unlockable as a permanent stage once clearing Floor 10 from the Heavenly Tower.

Strategy[]

The key to beating Realm of Carnage is to kill the Bores and R.Osts quickly in order to whittle down Hannya's 1 million health before more appear and give you further trouble, all while under constant fire from the extremely damaging attacks. In other words, the higher your cats' levels, the better; level 30 Crazed Cats are especially recommended. Since this stage mostly focuses more on how strong your units are, anti-Red Uber Rare Cats also work great here, like Kuu. However, you will also need ranged units to take care of R.Ost, such as Dragon Cat or Crazed Dragon Cat.

Recommended Units[]

The following cats are basically required for some strategies, or at least can make the stage much more manageable.

  • Island Cat: One of your main attacking forces if you don't have any decent Ubers. Can be replaced with a hypermaxed Manic Island if your Island Cat is underleveled.
  • Crazed Whale Cat: Combining monstrous stats for an extremely low cost, Crazed Whale Cat is a central part of beating this stage. At level 40 with True Form and some "Strong" Effect UP Combos, Manic Island Cat can instantly destroy the Ginger Snaches.
  • Fried Shrimp Cat: Can effectively stall Hannya because of their humongous health against Red enemies, doubly so in True Form. Their weaken can also help certain units like Awakened Bahamut Cat or Greater Balrog Cat to tank extra hits, although it is rather unreliable.
  • iCat: iCat requires very good timing and either the Move Speed Up talent or, with luck, Fried Shrimp's weaken to work. With one of these two options, iCat can rush down Hannya and freeze the boss, giving other units time to get more damage in. Despite his difficulty to use effectively, iCat can still make this stage much more manageable than before if he is able to land a hit, potentially allowing Hannya to be taken down before R.Ost could even arrive.
  • Elemental Duelist Cat: Can be a very useful asset in rush strategies if you boost him to level 33 or higher, as that allows him to survive a hit from a weakened Hannya, if you are also using Fried Shrimp Cat. A few of them will tear through Hannya quickly.
  • Power Cutter Cat: Immune to weaken, extremely fast, survives a lethal strike and strengthens by 400% at 1% health. Quite disposable for how much damage it can easily inflict on the red enemies encountered here.
  • Courier Cat: Courier is fast, cheap, has a low cooldown and does massive damage to Reds with good stats to begin with. At level 40 with max Blood Fruit Treasures, its damage shoots up to over 36k, destroying the Red threats with terrifying ease when used properly. Even Hannya will fall victim to these devastating attacks as Couriers get more and more hits in.
  • Lone Cat and Kitten/Tourist Cat: With Resistance/Knockback/Freeze versus traitless enemies, they can disable R.Ost, and make timing Awakened Bahamut extremely simple. They also come from a very easy Advent Stage that can be cleared before this.
  • Awakened Bahamut Cat: With his quick speed and high damage, he can devastate the R.Ost if timed well. Additionally, he can land a blow for some quick damage on the boss when undefended.

Recommended Ubers[]

The following Uber Rares are good for this stage, and if you have any of these, using them will make things easier.

  • Pai-Pai: The designated "counter" to the stage with massive damage/insane resist to reds and weaken immune. Soaks up hits from those reds like no tomorrow and can make short work of both Bore and Hannya. Her range also allows her to act as support against R.Ost.
  • Tesalan Pasalan: A sure-fire way to get rid of a Bore or R.Ost. Sadly does not outrange Hannya but can still guarantee a quick kill on the support to give you more breathing room.
  • Tropical Kalisa: Excellent nuker against both Hannya and Bore. If timed correctly she can put on some major damage to the boss.
  • Eva Unit-02: Better in True Form, is able to dish out massive damage to Hannya and Bore while also being able to tank some hits from Hannya and can even hit Hannya from behind a Bore or R.Ost if positioned correctly.
  • Greater Balrog Cat: Only works in True Form, and if upgraded to minimum level 40, preferably with augment from talents. His weaken immunity, disposability and high single-target damage can be used to great effect against Hannya and Bore. At even higher levels, Balrog can also help taking out R.Ost.
  • Kuu: Strong against reds, has Weaken Immunity and high damage, able to obliterate both Bore and Hannya, as well as tank hits from any reds here.
  • Peach Devils: Can quickly infiltrate into Hannya’s range freezing him and can help perma-freeze Hannya with Icat to follow up. Also can help with the Bore.
  • Goddess of Light Sirius: Since you're likely running Strong combos anyway, Sirius gets major improvements to the point where she becomes overpowered, shredding Hannya and the Bore. Also has good DPS against the R. Ost as well.
  • Any EPICFEST Ubers: Can quickly take out the R.Ost to give more breathing room.

Strategy 1[]

Lineup:

Lineup: Seasons of Love, Eraser Cat, Fried Shrimp Cat, Crazed Whale Cat, Island Cat, Crazed Dragon Cat, Dragon Cat, Awakened Bahamut Cat

Notes:

  • Main units must be at a high level (at least 20+35 for Normal Cats, 30 for Crazed Whale Cat), True Form if possible.
  • Battle Items: Rich Cat (optional but helpful), Treasure Radar (only if you're sure you can beat the stage).
  • Cannon: Default or Thunderbolt.
  • The best set of raw power-related Combos you have (Seasons of Love/Three Kings/Lion King recommended), Dragon Cat (unless included in the Combos)
  • Combos may be replaced by other cats such as Power Cutter Cat or Fried Shrimp Cat.

Start off by deploying some Crazed Whales to stall Hannya, while also upgrading your Worker Cat to Level 3 or 4.

Bore phase: When the first Bore arrives, use Island and Crazed Whale to stall and continue slowly upgrading your Worker Cat. Killing the Bore before R.Ost arrives is crucial as dealing with them both will be extremely troublesome, so add Crazed Dragon if needed. When the Bore is defeated, continue deploying Crazed Whales and Island Cat to deal some damage to Hannya.

R.Ost phase: When he arrives, stop deploying them, instead spam Eraser and summon Awakened Bahamut, Crazed Dragon and King Dragon to damage the R.Ost, all while continuing to slowly upgrade your Worker Cat. Awakened Bahamut should easily take R.Ost down if timed well. A good way to do this is to send out one Eraser when the R.Ost is really close (next to your base), and as soon as R.Ost attacks your Eraser, send out Awakened Bahamut. Then, spam meatshields after R.Ost gets knocked back. This strategy to time Awakened Bahamut could also be done with Thunderbolt for an even easier timing. After Bore's death, start sending only Crazed Whales and Island Cats out to damage Hannya. Repeat the above when the Bores and R.Ost arrive and you should be able to win the stage eventually.

Note: Manage your money properly and do not unnecessarily deploy cats, or it may result in your loss.

Variations:

  • Crazed Dragon and/or Awakened Bahamut may be replaced by 1 or 2 adequate Uber Rares, like Pai-Pai Z or Divine Kuu and/or a mid-ranged unit like Paris Cat; all that changes is what the Bore and R.Ost killers are. Units like Paris Cat may work for R.Ost, Kuu is ideal for the Bore, while the likes of Pai-Pai can handle both.
  • Eraser Cat can be replaced by other meatshields, as long as they are strong; Maximum the Fighter is the best choice, but Jiangshi Cat and Crazed Wall Cat/Manic Eraser Cat also work, while 75¢ cats do not, as they'll be shredded by the support here.
  • Recommended Combos could be swapped for Attack-based ones, but 90% of the time it is better to go with strength and defense, as units struggle to reach enemies to deal damage in the first place. The only part where damage is better is the Bore, so only use an Attack Up Combo if the Bore can be stalled but takes too long to kill.
  • Fried Shrimp Cat may be added in place of a cat on the first row if a different set of Combos is used or in place of one of the "two attackers" (Awakened Bahamut Cat and Crazed Dragon Cat), doing so is only recommended if the enemies push so much that the defense isn't enough.
  • Lion Cat and other cats that may be here for Combos should never be used, but a fast unit like lion may still be used for quickly reaching Hannya in case of an emergency, it could be better in some cases and worse in others, but it makes little difference.
  • Less Combo cats for more variance in the army may be a viable strategy, but it is highly unrecommended unless the units one owns don't allow good enough Combos.

Strategy 2 (ft. Roe Cat)[]

Lineup: Biohazard, Bony Bone, Awakened Bahamut Cat 30, Crazed Macho Cat 20, Crazed Wall Cat 20, Courier Cat 40, Manic Island Cat 20, Roe Cat 30

Cannon: Thunderbolt

Items: Rich

Notes:

  • A level 31 crazed Whale can work in substitute of a level 20 Manic Island
  • Crazed Cat and the extra slot can instead be used for the Mini-Saurus Cat Combo using Lil' Cat as a meatshield or the extra slot can be used for an Uber if wanted.
  • Default Cannon can substitute for Thunderbolt
  • This strategy does require a bit of luck with Roe Cat's Weaken ability.

Battle: Put out about 3-5 of both your Crazed Wall and Crazed Cats out to stall the Ginger Snaches until the Bore comes out. Once the Bore comes out stop meatshielding and start putting out Manic Island Cats, Roe Cats, and a couple Courier Cats once the Snaches are right by your base. After the Bore is in front of Hannya by 1.5 times Hannya's attack range start spamming Courier Cat, Manic Island Cat, Roe Cat, and your meatshields. Your stack should kill or nearly kill the Bore before Hannya attacks them. When the Bore dies your Roe Cats need to weaken Hannya so A. Bahamut can get multiple attacks off. Wait until Hannya attacks before putting out A. Bahamut. Then keep spamming your cats mentioned before. Hannya should die before R. Ost can reach you. Just keep spamming your attackers and eventually R.ost should die. Enjoy a free and easy Express Cat!

Strategy 3[]

Lineup: Cap'n Ahab, Moby Dick, Island Cat 20+28, Manic Island Cat 30, Manic Eraser Cat 30, Roe Cat 36, Manic King Dragon 30, King Dragon Cat 20+41, Vendor Cat 30, Courier Cat 40, iCat 30

Cannon: Default

Items: Rich Cat

Notes:

  • Rich Cat is optional.

Start off by deploying a Roe Cat and some Manic Islands to stall out Hannya. Upgrade your worker cat to level 3.

Bore phase 1: When the first Bore arrives, let everything die. Once the Bore gets a bit out of Hannya's range, spam everything except Doctor Cat and Vendor Cat. Once the Bore is permafrozen, stop sending Manic Eraser. The bore should die relatively quickly.

Hannya phase: You should have two ICats up by this point, so use the Cat Cannon to reset Hannya's attack and let them get in. A lot of damage should be dealt here. Stop spamming ICat if you have enough to permafreeze Hannya.

R.Ost + Bore 2 phase: When he arrives, stop sending out Roe, Courier, and ICat, and prioritize your Dragons and Vendor Cat. Feel free to send out an Island Cat if you feel R. Ost is pushing too hard. The Bore should return at this point, so when he arrives, start sending out Courier too. Once the R. Ost dies, revert to Bore Phase instructions.

Ending: After the first Sir Seal comes, Hannya should be dead, so just keep spamming everything but Doctor Cat, and it's an easy win.

Note: Manage your money properly and do not unnecessarily deploy cats, or it may result in your loss.

Variations:

  • ICat can be replaced with a better unit like Ice Cat's true form.

Trivia[]

  • The River Styx is a river from Greek Mythology which marks the boundary between the world of the living and the Underworld.
  • Although River Styx' and Courts of Torment's Japanese names can both be translated as "Hell Gate" or "Gates of Hell", they don't refer to the same hells: River Styx is spelled with jigoku (地獄), the generic Japanese word for Hell. Courts of Torment, on the other hand, is naraku (奈落), which refers to a Naraka, the Buddhist equivalent of Hell.
    • Interestingly enough, Hannya's Japanese description mentions that she consumes the souls of those who cannot gain enlightenment, with the term used, jōbutsu (成仏) specifically referring to attaining Buddhahood.
  • In the Japanese Version, this is the only Advent Stage whose name does not include the level's difficulty.
  • Prior to April 2017 (February 2018 in the English Version), this stage had no known schedule.
  • Realm of Carnage was added in the same update as Pai-Pai, Version 5.3, as though it was designed specifically for her to counter.
  • The enemy base's HP is composed of two 666s, believed to be the "Number of the Beast".
  • This is the second advent stage to be added in The Battle Cats Unite! as it was distributed in the 1.0.7 December 15, 2023 Live Download Patch.
