Most players probably already know this, but there are plenty of Aesir, Elves and Therians can easily clear this CB, but the issue is Shade. Well, sometime in 2021, during the Overlord Collab, there is a free way to get around this issue. There is an item in the Overlord Cards called "Ainz Ooal Gown's Ring", which gives MATK/MDEF 30% x 2 turns (opener) and Shade Resistance 80% Up (constant) to anyone in the Magic or Ranged Row, which opens up a lot of options for less fortunate players, and if you were unable to beat Medjed 9*, this can help out a lot with that.
Any other comments, opinions or concerns?

*Edit: Anyone can use this ring, not just Magic or Ranged characters. My apologies.

I am sure Seraphel users will be happy to hear that!

Therians in particular have access to an older item if you have it called Garm's Candy Bucket which is also Shade Resistance 80% Up (constant).

You're right, I forgot to mention that one. Thanks.

Auto Farm Setup (No Sortishia)

Karyo's picture

Finally got this boss on farm after the recent Seven Deadly Sins collab. This is a good boss to start EX on because coins from this boss will get you Unholy Eye of Nidhogg necklaces which increases damages against beasts. Since most of EX connect bosses are beasts, the necklace will help with those connects.

Here's my setup:

(1) Imperial Knight Viola

  • Halo Sword, Heraldic Edge, Rei's Ordeal Scythe, Wing Shield
  • Bangle of Strength, Ring of Niflung, Rainbow Pendant, Sun Watch
  • Black Dragon Axe

(2) Escanor

  • Gold Feather Blade, Raging Thunder Blade, Heraldic Edge, Asgard Blade
  • Bangle of Strength, Bracelet of Conflict, Kvasir's Blood Chalice, Slayer Ring
  • Crystalline Pulverizer

(3) Transcendent Utgardar

  • Universal Crown (Sp.), Nemesis Rod, Solar Staff, Spring Light Staff
  • Bangle of Wisdom, Demon Blood, Hellish Blizzard's Necklace, Ring of Conflict
  • Crystalline Caster

(4) Elizabeth

  • Purification Staff, Lucy's Fleuve d'etoiles, Keraunos MK III, You-know-who's Boots
  • Ainz's Wristwatch, Bangle of Wisdom, Demon Blood, Laxus's Magic Headphones
  • Black Dragon Staff

(5) Spear Knight Geirrod

  • Despair Ring, Genesis Disorder, Halo Sword, You-know-who's Boots
  • Bangle of Strength, Bracelet of Conflict, Kvasir's Blood Chalice, Gaia's Protection
  • Crystalline Piercer
