[DFFOO] Leviathan Event and CHAOS Boss Overview

World of Illusion – Ultimate Leviathan is arriving on 11/17 at 6PM PT (11/18 2AM UTC) and with it comes the ability to level the summon Leviathan to level 30! It also unlocks a new summon board that you can earn points and power up your characters. In order to unlock Ultimate Leviathan, you must first level your Leviathan to level 20; so if you haven’t done that, you better get cracking. In this article, we’ll share a brief overview of the event, and then dive into a detailed overview of the CHAOS level boss.

Special Boosted

For this event, certain characters are special boosted. They are: Krile, Zell, Shantotto, Laguna, Tifa, and Kefka. If one of these characters are used, your entire party will gain double summon experience points!

Krile and Zell will be on banner featuring their EX which can be realized (EX+), with Laguna who will not have his EX.

The second banner will feature Kefka’s EX and Tifa’s EX (not realizable) and Shantotto without EX.

CHAOS Overview

Leviathan will open the fight with Tidal Wave+, giving himself 20,000 BRV, changing his elemental resists, buffing himself for 1T with Leviathan’s scales, and causing a field effect called Maelstrom. Maelstrom inflicts sap and will steal 6,000 BRV increasing as the fight goes on and his HP threshold auras take effect.

At the 80% HP threshold, Leviathan will increase all of his stats, and Tidal Wave+ will start giving 40,000 BRV. At 50% HP threshold, Leviathan will increase his stats even more, and Tidal Wave+ will give over 60,000 BRV!  So in order to tackle this CHAOS level, you need to be prepared to deal with over 60,000 BRV at once. This means using characters that can poison, sap, gravity, freeze, or deal huge amounts of BRV damage.

BRV Damage: Krile (3/3 EX+), Zell (3/3 EX+), Cloud (3/3 EX+), Garland (3/3 EX+), Tidus (3/3 EX+), Fang (3/3 EX+), Paine, Vayne
Gravity & Sap: Sherlotta
Poison & Sap: Serah
BRV Freeze: Setzer
Tank: Warrior of Light (EX+, 3/3 not required)

Krile and Zell have their shiny new EX+ toys, and if you happened to fully realize them, they can bring BRV damage to the table. Krile’s EX also batteries the party, helping to prevent you from breaks. She also has the added benefit of Thunder weakness, making her the premier damage dealer for this fight.

Cloud is another obvious choice here, because Leviathan is not immune to paralyze. This will help you delay the boss so you can shave him down. Cloud will also dispel Leviathan’s scales buff, which is a DEF and SPD buff immediately after Tidal Wave.

Garland is a powerhouse in this fight, delaying with each of his abilities and dealing huge amounts of BRV damage.

Tidus and Fang both bring excellent DEF down debuffs as well as good damage with fully realized EX+ weapons. Tidus can also abuse his free turn abilities to re-break Leviathan if Tidus is inflicted with Sap (as the Sap BRV damage will bring Leviathan out of break status!).  Fang can also launch which can help with extra BRV shaving attacks, and give the party the ability to do extra burst damage with her C65 (AA) ability for 9 total turns.

I thought I would make a note of PaineVayne, and Setzer as there were JP clears using these characters. See the video links for more info.

Sherlotta and Serah are obvious choices for support in this fight. Sherlotta brings both Gravity (EX) and Sap (Hurl Staff), along with huge battery, 20% HP damage boost, etc. On the other hand, Serah brings a framed debuff [Goddess’ Light] which is DEF down 20% and Poison (EX), and an additional Poison (Wound).

Lastly, bringing Warrior of Light to this fight will make it a lot more manageable as Leviathan has many AOE attacks which can overwhelm you. WoL’s shield will allow you to focus on DPS / shaving. Keep in mind that this also means you’ll have to compensate for WoL’s lower damage. This boss has a TON of HP and the turn requirement is tight. This is the highest HP boss in global to date, but hopefully this article has prepared you!

Good luck everyone! Also, a small reminder that if you’ve done all the CHAOS so far, this is the 20th weapon nugget == another Ingot!
