Revival: Rashomon - Challenge Quest Guide

• Rashomon’s Challenge Quest is similar to previous events by having an enemy rush with no reprieve right from the start. The fight consists of a 3M HP Ibaraki with the paired Oni’s Arms from every “day”, starting with the Archer class Oni’s Arms and proceeding through the release order of Caster, Assassin, Lancer, Saber, Rider, and Berserker Arm versions, all fought in a single wave. With the exception of the Archer Oni’s Arms having less HP, all Oni’s Arms have the same HP as their forms in the 3BP raid. As their names imply, Oni's Left Arm and Oni's Right Arm can only spawn on Ibaraki's left and right side, respectively.

• Ibaraki will start the fight with 14 stacks of her special Damage Resistance and an infinite duration and refreshing Guts. In addition, Ibaraki will have access to all special skills showcased with each “day’s” different class Oni’s Arms, and will automatically cast these skills in order of each “day” cycle when there are 15, 13, 11, 9, 7, 5, and 3 enemies left. Ibaraki will do this automatic skill immediately on her next available non-NP action, although charming or stunning Ibaraki can delay when she uses the skill by an extra turn.

• Ibaraki’s Damage Resistance and special Guts can be removed by defeating the Oni’s Arms, with 1 stack of Damage Resistance removed per Oni’s Arm defeated, and the Guts removed when all Oni’s Arms have been defeated. While it’s possible to deplete Ibaraki’s HP bar with brute force before all Oni’s Arms have been defeated, Ibaraki takes trivial amounts of damage until there are 4 or less Oni’s Arms remaining, making it difficult to trigger the Guts (which is infinite) before all Oni's Arms have been defeated. Do note that, like Ibaraki’s automatic skill usage, the automatic Guts removal will not occur if Ibaraki is charmed or stunned as it requires Ibaraki to act that turn, though the automatic removal of Guts will not count as one of Ibaraki’s available actions that turn.

• For most Masters, Mash + Damage Servant + Merlin/Tamamo/Zhuge Liang will be an easy-to-field set of Servants when considering Friend supports, team durability, and damage output.

• As far as damage dealers go, there are plenty of good options. From a class perspective:

  • - Provide consistent damage despite enemy class, though, as always, they remain glass cannons.

  • // - Trade improved damage against all but Berserker for neutral or half damage taken from all but Berserker enemies. BB is likely the most available option Masters have from these Extra classes.

  • - Because the Archer Oni’s Arms have dramatically lower HP than normal, a Saber class Servant shouldn’t have too much trouble defeating the Archer Oni’s Arms. To provide context, a Saber class Servant has about as much trouble defeating the Archer Oni’s Arms as they do the Assassin Oni’s Arms, and an easier time than the Rider and Saber Oni’s Arms by HP values alone.

• All Servants still benefit from the Damage Bonus provided by the Event CEs, and they are the premiere options to field for every Servant much like with the normal raids..

• For reserve Servants, it’s better to focus on support-oriented Servants over additional damage dealers due to limited party size and possible lack of extra Shana-oh CEs. In other words, it’s better to focus on keeping your original damage dealer alive than it is to rely on a new damage dealer at the end of the fight.

• For specific support-oriented Servant recommendations, click on the Accordion below. Support Servants are the key to success and with the right combination is much more important the selecting the right damage-dealer.

• Because a list for specific damage Servants from all available would be too long, this list will talk about effects useful to have for the challenge quest. Servants with at least 2 of the following are decent options to consider:

  • / Evasion or Invincible (personal or party)

  • Defense Up (personal or party)

  • Healing (party)

  • NP Battery

  • Stun or Charm (generic purpose is best, but at least against Females or Servants)

  • NP Drain

  • A throwaway skill to negate Nullify Buff, preferably party-wide

  • Attack Down (enemy party-wide preferable)

  • Critical Rate Down (enemy party-wide preferable)

  • Critical Star Absorb for 3 turns (assuming a good source of Critical Stars already exists)

  • Cleanse

• Because it's vital to defeat most, if not all, of the Oni's Arms before being able to tackle Ibaraki properly, it's more important to build a team that can survive the coming onslaught than it is to have a team with great damage potential. In fact, Masters can stall out the entire Challenge Quest with a full stalling oriented team featuring only the top supports. 

Dealing with the Oni Arms

• Focus on preventing any of the Oni Arms from firing off their special Attack as their accompanying Stun/Skill Seal can be utterly lethal for the unprepared, prioritize whichever Oni Arm will be the next to fire their Special Attack.
• Since the Left Arm has the smallest NP bar gauge of the three enemies, it will generally be the first target to be destroyed. However, if its bar progress lines up with Ibaraki's, it might be worth ignoring it for a turn since Mash, or some other Target Focus Servant, will be able to take the Left Arm's NP before Ibaraki's NP without issue.
• Prepare Defensive Skills or NPs for the Oni Arms that counter the current team.
• it's generally best to aim to defeat both Oni's Arms on the field at the same time, as this will reduce the number of actions from Ibaraki's side (she moves 2x at most).
• That said, if there are an odd number of enemies remaining (apart from the final one) after defeating an Oni's Arm, Ibaraki will use up one her actions to automatically cast a skill rather than attack.
• Be careful with the Rider and Caster Oni Arms - they are both capable of charging Ibaraki's NP Bar, possibly charging her NP before the required survival skills are off cooidown. Saving an NP ahead of time and unleashing it right away on them is a great way to reduce any random element. 
• Be prepared to deal with large incoming damage for the last 4 Oni Arms considering most compositions will feature a Caster. 
• Oni Arms can only spawn on their associated side. Rushing the Left Arm will leave Ibaraki with both her Right Arm harassing you and with her acting twice per turn (which is more lethal).

Other Points of Advice

• Stunning or Charming Ibaraki will not cause her to skip over a scripted skill activation, it generally merely delays it. Skill Sealing her should work however (unverified).
• Ibaraki is perfectly capable of using any of her event-only skills. The most dangerous of these skills are those that cause Buff Block and NP Seal.
• Defense Up buffs work best at preventing freak focus fire or heavy critical damage deaths given Ibaraki's high base damage. Reactive Burst Healing is rather ineffective if a Servant died in a single turn after all. 
• Attack Down and Defense Up buffs stack additively - this will greatly reduce incoming damage and if stacked high enough even allow Mash to tank an NP directly. 
• Guts skills do not work against Ibaraki's NP, she will remove it before it can trigger. 
• Critical Damage and NP Damage buffs stack additively with the Event CEs.
• If all else fails, Command Seals are available and Masters can even wait for the daily reset to get an additional Command Seal (even after the event closes)! Masters will still receive that tasty Summon Ticket.

  • Mash, Raikou, Merlin, Merlin, Zhuge Liang, unused Cu - General fight information

  • Gorgon, Merlin, Zhuge Liang, Mash, Andersen, unused Altria (Lancer) - Shows how stuns can delay Ibaraki's automatic skill usage actions.

  • NP1 Cu Alter (level 100 Shana-oh) "solo" with 5 Target Focus Servants using mlb Golden Carp - While the CEs are a bit much, this approach can be mimicked by using CS to force Cu Alter to NP earlier.

  • Mash, Jeanne Alter Lily, Merlin, Chloe, George, Leonidas - This setup uses Servants and CEs that Masters who have been playing regularly should have, even as F2P.
