Unit ills full 20234

"Sorry for the hold up! Alright, let's do this!!"


Brave Knight Karl, similar but not identical to Karl of the 24th Division of Demon Slayers, is a Mock Unit located at the Summoners' Research Lab in Imperial City Randall. The fight itself is composed of a single battle against Karl's two forms, Brave Knight Karl and Ice Warrior Karl. He is only obtainable through the completion of Trial No. 001. 



You may use up to 3 squads and 1 item set for this battle. Each of the squads must have unique units in them and you are allowed up to double your total cost. You select a different friend from your entire friends list for each squad that you can bring in. There is no cooldown when using a friend to fight Karl. Your items do not get replenished when a team dies, so bring as many healing items, elemental seals, and status cure items for paralysis/weakness as you can for this fight.

Water and Fire Elemental Units are not recommended since Karl can use Water, Thunder, and Earth based attacks.

Squads recommended:

  • Thunder/Water (most highly recommended)
  • Light
  • Earth
  • Dark

Recommended Leader Skills:

  • 15%-30% Hp boost with added effects if needed
  • Divine Gale (nullifies all status ailments)
  • Ares' Excelsior (Boost in BB Gauge fill rate)
  • Boost to drop rate of BC (During Spark or Not, still useful)
  • 65% Boost to ATK Power when five or more elements are present (50% if Five Light's Order isn't present as the leader skill.)

Units Recommended:

Alternatively, you can just equip at least 1 of your units with the Guardian Cloak. It will take a while to beat him as you have to chip away at his health slowly. Be sure to use it on a unit with moderate damage so as to outdo his healing after he reaches below 15% hp on his 2nd form

Mono-Thunder Squad

The easiest (and more straight-forward) way to beat Karl involves bringing a mono-Thunder team of max level 5, 6, and 7 star units.

Possible leaders:

  • Gilded General Weiss - Small reduction in BB gauge amount consumed during BB & large boost to drop rate of BC produced during spark
  • Thunder Legend Eze - 100% boost to Atk power and 30% increase in HP of Thunder types
  • Celestial Archer Loch - 100% ATK Boost and 30% DEF and 50% to Spark damage to Thunder Types
  • Holy Shock Emilia - 50% ATK Boost to Thunder Types & fills BB gauge after each turn
  • Gold Queen Rina - 65% ATK Boost to Thunder Types
  • Mech God Grybe - 15% DMG reduction from Water Types & boost to damage dealt to Water types from Thunder types
  • Valkyrie Archangel Griel - Nullifies all status ailments, boost BC and HC drop rate, & 30% boost to HP

Immortal Beast Sargavel is an excellent substitute for Griel for removing and nullifying status ailments. Also, Loch is an excellent choice even if he is not the leader.

Select one (or two if you are worried) of three possible healer units to select based on your luck with rare summons. At the very least use a max-level Royal Dancer May (healer) that is Anima type and have BB level 10:

Three remaining squad members should preferably be Anima/Lord/Guardian/Breaker type. First choices would be any of the units listed above in having desired leader skills. Other solid choices are:

Each unit should be equipped with a stat-boosting sphere. Flesh Armor/Limbo Stone are okay, although all stat boost spheres such as Sacred Jewel/Medulla Gem would work better. Recommended items include Thunder Ores, Thunder Seals, Fujin Potions, Fujin Tonics, Revives, Cures, and Stimulants. Use Fujin Potions as an emergency catch on your healer if you're caught with an unlucky BB string from Karl.
