Xeno Cocytus Clash is a clash event that rewards items used to trade for the Xeno Glacial Dream Staff and Dante's Harp weapons.

It is an expansion of Cocytus Showdown and the associated battles are also available during the event.

For new players

This event is fairly difficult for new players, with Xeno content being harder than the basic Showdown and extremely punishing to players without Earth teams.

  • The normal Cocytus Showdown is also available, however, which can be used to gather most of the basic trade-in treasure for items from the Xeno event shop. Note that the inventory and material costs of the Xeno shop are separate from that of the normal Cocytus Showdown shop.
  • If nothing else, purchase the 20× Half-Elixirs; they provide much more AP than is needed to farm them.

Xeno Weapon

Xeno weapons have a Massive EX ATK weapon skill. For newer players, even a 0★ copy of a Xeno weapon is a strong addition to most grids and can be feasibly obtained by leeching the Event Raid or defeating NM70 a few times (if possible).

Other Rewards

  • Vergilius sees niche use in grids that require HP while still providing attack. It is available at all times from the normal Cocytus Showdown, making it a very low priority in the Xeno shop.
  • Cocytus is an older summon with a weak aura and an acceptable call. It can see use as a filler summon if upgraded to 4★, but should not be prioritized as it is available from the normal Cocytus Showdown shop.
  • Xeno Cocytus has a strong Elemental ATK boosting aura if the weapon requirements can be met, and comes with a good Water ATK boost on call as well. Materials for copies and 4★ uncap are only available during this event. Note that Leviathan Omega also provides Water ATK at 4★ or higher and is permanently available.

About Clashes

Clashes and Showdowns

  • Play Xeno Cocytus Clash and Cocytus Showdown at the same time!
Clash battles are harder than showdowns. When you are able to clear extreme- or maniac-difficulty showdowns you should be able to take on Xeno Cocytus (Note that Xeno Cocytus's resistance to elements other than Earth is notably high, meaning this statement is more of a guideline than hard truth).

Difficulty Settings

  • Xeno Cocytus maniac-difficulty will unlock after clearing extreme-difficulty.
  • There are three levels of nightmare battles. Defeat the lower-level nightmare bosses to unlock the next one. Play to get treasure for the new event weapons!

Nightmare Battles

  • Nightmare-difficulty quests will always appear after clearing a maniac-difficulty quest. They will also appear after clearing four consecutive extreme-difficulty quests if one has not already appeared by the third time.
  • Only one nightmare-difficulty quest will appear at a time.

Elemental Resistance

  • Xeno Cocytus now has 50% damage resistance to all elements except for Earth.

Xeno Weapons

  • You can get Xeno weapons from this event.
  • Xeno weapons can be forged into their True Xeno forms at the shop. Exclusive treasure from this event is needed to forge the xeno weapons.

Changes from Previous Xeno Cocytus

  • AX skills have been added to Xeno weapons that drop by defeating Xeno Cocytus.
  • Certain items' drop rates have been adjusted.
    • Drop rates have been increased for the Xeno weapons Xeno Glacial Dream Staff and Dante's Harp with the addition of AX skills.
  • The following items have been added to the treasure trade.

Farming efficiently

After the drop rate increases, with average luck, there's a decent chance of at least one drop while gathering Frozen Hellplume and True Xeno Cocytus Anima required to forge Xeno weapons into their true forms (and uncap to 5★).

Priorities:

  1. Complete Event Missions for guaranteed copies of the event weapons.
  2. Do both of the daily maniacs (Xeno and Old Cocytus).
  3. Do the highest Nightmare possible to maximize Frozen Hellplume drops.
  4. Host the raid once you have over 40× Frozen Hell Prism
  5. Delay any purchases from the shop until you've acquired all the trade-in materials for all purchases you have in mind. Purchasing early may lead to a drop happening for that item whilst you farm for other items. The drop would be worthless and you will have wasted time. Be sure to account for the cost of any uncaps you are aiming for as well before making your purchases.
Expected resource cost
Can solo NM120 1250~2800 AP 0 EP Assumes 10 Xeno Maniacs.
Can solo NM70 3000-7000 AP 0 EP Host raids to reduce cost.
Leeching the raid 0 AP ~1200 EP ~400 raids needed for the Frozen Hellplume.
Necessary Materials
Material Assuming 0 drops Comment
4★ Xeno Weapon 5★ Xeno Weapon 4★ Xeno Summon
Crystal Spirit 190 190 283 Enough will likely drop while triggering NM.
Frozen Hell Prism 40 40 30 Save enough for forging, use the rest liberally to host raids.
Frozen Hellplume 45 85 143 NM120 drops 3-4. NM70 drops 1-2.
Cocytus Anima 100 100 - Farm extra EX/NM70 as necessary. Do the Maniacs.
Cocytus Omega Anima 90 90 202 Farm extra EX/NM70 as necessary. Do the Maniacs.
True Xeno Cocytus Anima 23 43 115 Leeching raid nets ~0.4 True Xeno Anima. 60% in red chests.

How to maximize Xeno weapon drops

  • Raid red chest can drop a Xeno weapon. It's ~1.5% in the Host chest and ~0.5% in the MVP chest.
  • The increased drop rate from NM120 is cancelled out by being able to bring Kaguya (Summon) to NM70. It takes about 2.8 Extreme clears to trigger one NM.

Trivia

Etymology

Many of the names and terms in this event are derived from the Divine Comedy written by the Italian poet Durante degli Alighieri, or simply known as Dante. The Divine Comedy is widely considered the preeminent work in Italian literature and one of the greatest works of world literature.

  • Canticum means "song" in Latin and is the origin of the English word "canticle." The Divine Comedy itself is divided into three canticles: Inferno (Hell), Purgatorio (Purgatory), and Paradiso (Paradise).
  • In Dante's Inferno, Cocytus is the ninth, and lowest, circle of hell where Satan resides and chews on the heads of the three traitors. Cocytus is a frozen lake and is that special place where traitors and fraudsters are sent, according to the series.
  • Cocytus itself is divided into four concentric rings (or "rounds"):
    • Caina, named after the Biblical Cain; traitors to blood relatives.
    • Antenora, named after Antenor from the Iliad; traitors to country.
    • Ptolomea (Tromea), after Ptolemy, governor of Jericho, who murdered his guests; traitors to guests.
    • Judecca, after Judas Iscariot; traitors to masters and benefactors.
  • Divina Commedia is the Italian title for the Divine Comedy
  • Vergilius, commonly known as Virgil, was a famous ancient Roman poet who also appears as Dante's guide through Hell and Purgatory in the Divine Comedy.

This theme is also present in the original Cocytus Showdown.
