Overview

This battle is very similar to the "Beast of Taming" battle during the Olympus chapter, with the boss having the same skills and break effects as before. However, the NPC Supports available and additional helpful field effects are new.
Ibuki-Douji in particular comes with helpful permanent debuff immunity, invincibility against NPs for 3 hits, high star weight, and 10 stars per turn.
- Due to how powerful her NPC Support version is for this battle, it is entirely possible to defeat the boss with NPC Ibuki as the primary damage dealer with minimal support (see video links).
Additional helpful effects will occur every 2 turns, rotating in order:
- Skill Seals and drains boss's NP by 1, and provides small ATK buff to allies.
- Removes 3 buffs from enemy and clear 3 debuffs from all allies, adds Near Water field, restores 500 HP to lowest-HP ally.
- Stun (80%), Curse (4k dmg, 8 turns), amplify Curse damage (100%, 8 turns), and Buff Block (3 times, 8 turns) the boss.
The Boss is Beast IV class, and has advantage against [Hominidae] Trait Servants (2.0x damage) and Defense Class Disadvantage against [Demonic Beast] Servants (2.0x damage). Otherwise, they also deal 0.5x damage to Caster Class.
The Boss has a large 80% NP Damage / 60% Crit Damage Resistance for the first three turns, so it can be difficult to deal damage to the boss in the initial turns.
At battle start, the boss gains Crit Rate, Invincible, 1 extra NP Charge per turn, and debuffs ATK for the frontline. Note these are removable buffs.
Curse and Curse Damage Up effects can be inflicted by the boss's Skills and NP, and can stack.
The Boss can inflict Terror (chance of Stun each turn), along with an On-death debuff that will heal the boss by 50k / give it an ATK buff when the debuffed Servant dies.
The Boss also has a 5-time, 2 turn Evade skill with 80% chance success, which can be randomly used as a skill during its turn.
1st Break: Charges NP to max, buffs its own Crit Damage, and debuffs the party's DEF and Star Drop Rate.
2nd Break: The boss Stuns itself for a turn, loses 1 NP bar, gets a DEF debuff, while the party gains an ATK buff, 20% NP Gauge, 1 debuff cleared, and 20k HP recovered.
3rd Break: Gains 1-time 120k HP Guts, charges NP bar by 1, an ATK buff, bonus damage against Debuffed enemies, and 5k HP recovery per turn.

Team Recommendations

Damage Dealers with [Demonic Beast] trait have Class Advantage for this encounter; they are a solid choice if available in the roster. On the other hand, avoid bringing Human attribute Servants unless the party is prepared for them to perish quickly.
- Caster Class has defensive Class Advantage as well. The one Servant currently available that has both advantageous traits is Tamamo-no-Mae. As a result, Tamamo survives surprisingly well for this encounter, and is a great choice to bring along if available.
Debuff Clear Support is extremely useful in this encounter to remove the Stun and Curse effects that the boss can use, along with any other deleterious debuffs.
Buff Removal can also be helpful, with Avenger of Shinjuku being a notable option, having Buff Removal as well as Class Advantage against the boss.
Evade/Invincibility Support can help the party survive the boss's AoE NP, particularly after the boss gains a full bar after 1st break.
Damage / NP Support is useful in helping the damage dealer quickly bring down the Boss's multiple break bars. Depending on the damage dealer's card color of choice, Skadi, Merlin, Tamamo, or Waver are all good options.
Last Stand Servants such as Heracles (Bond CE), Cu Chulainn (Alter), or Cu Chulainn can also help clean up the last hits of the boss if they are available.
