Fate/Accel Zero Order: Irisviel Boss Fight Guide

Back to Main Event Guide

General Overview:

Irisviel is the surprise welfare servant released in the Fate: Accel/Zero event. Aside from the initial Irisviel acquired from completing the Main Quests, the other four copies of her are obtained from defeating four different copies of the Black Grail in Bonus Quests. Each copy represents a different element (Water, Wind, Earth, Fire) and is of a different class.

The general battle plan against the Bonus Quests are to have an AoE Servant strong against the mob enemies, and a ST Servant strong against the boss Irisviel. We charge our NPs using the waves before the boss and then use them upon entry.

 

One burst from our mob clearer on the final battle should normally not be enough to clear the mob enemies. We can either put two AoE Servants in the frontline and keep our ST Servant in the backline or put an AoE and ST Servant in the frontline but keep another AoE in the backline just in case.

  • AoE Lancer or AoE Berserker
    • Suggested Servants: Karna, Altria Pendragon (Lancer Alter), Lancelot
    • Recommended CEs: Kaleidoscope / Damage Increasing CEs / NP Charging CEs

 

2)

  • AoE Berserker or AoE Lancer or Arash
    • Suggested Servants: Lancelot, Frankenstein, Karna, Arash
    • Recommended CEs: Kaleidoscope / Damage Increasing CEs / NP Charging CEs

Special mention goes to Arash who can not only provide huge burst but also immediately allow for a backline Servant to battle.

Backline:

  • ST Archer / ST Berserker
    • Suggested Servants: Gilgamesh, Robin Hood, Orion, Heracles, Vlad III
    • Recommended CEs: Kaleidoscope / Damage Increasing CEs / NP Charging CEs

Gilgamesh doesn’t have a ST NP but deals more than enough damage to justify him being on the team.

 

  • Others Damage Dealers/ Support Servants

 

-----

 

The strategy is similar for all three battles. First, we eliminate the early waves while charging the NPs of our AoE Servants as much as possible. Once we reach the boss wave, we use both AoE NPs to attempt to kill the Gluttonous Demons as well as damage Irisviel. We then either use Order Change or wait for our frontline to die to bring out our backline ST Archer/Berserker/s to burst Irisviel down.

Suggested Team/CE Composition:

Required, Suggested, Doable

 

Frontline:

1)

  • AoE Caster or AoE Berserker
    • Suggested Servants: Nursery Rhyme, Helena Blavatsky, Lancelot
    • Recommended CEs: Kaleidoscope / Damage Increasing CEs / NP Charging CEs
  • Helena is a very nice pick as she can also help charge the NPs of her fellow teammates.

 

2)

  • AoE Berserker or AoE Caster or Arash
    • Suggested Servants: Lancelot, Frankenstein, Helena Blavatsky, Arash
    • Recommended CEs: Kaleidoscope / Damage Increasing CEs / NP Charging CEs

 

3)

  • Support Servant
    • Suggested Servants: Zhuge Liang, Tamamo no Mae (for Arts), Hans Christian Andersen
    • Recommended CEs: A Fragment of 2030, Support CEs
  • We can use Tamamo if we’re running a lot of Arts Servants like Nursery Rhyme, Helena, Vlad III.

 

-----

 

Backline:

  • Jack the Ripper or Other ST Assassin or ST Berserker
    • Suggested Servants: Jack the Ripper, Carmilla, Shiki, EMIYA (Assassin), Vlad III
    • Recommended CEs: Kaleidoscope / Damage Increasing CEs / NP Charging CEs
  • Jack is nearly perfect for killing Irisviel thanks to her bonus damage to Female enemies. Carmilla also does well in the same respect to a lesser degree since she also specializes in damaging Female enemies.

 

  • Others Damage Dealers/ Support Servants

 

 

-----

 

 

All three battles follow a similar strategy. We first kill the early waves while charging the NPs of our Servants as much as we can. We then immediately use them when we get into the boss wave, killing the Hassans, so we can concentrate on Irisviel. We then swap to our backline ST Servant by either using Order Change (or by waiting for a frontline member to die,) and burst down Irisviel.

Frontline:

1)

  • AoE Rider
    • Suggested Servants: Iskandar, Francis Drake, Altria Pendragon (Santa Alter)
    • Recommended CEs: Kaleidoscope / Damage Increasing CEs / NP Charging CEs

 

2)

  • ST Rider
    • Suggested Servants: Anne and Mary, Ushiwakamaru, Queen Medb
    • Recommended CEs: Kaleidoscope / Damage Increasing CEs / NP Charging CEs   

With Anne and Mary, The Black Grail is recommended as their equip CE as it synergizes well with their increased NP damage per missing HP.

  • Support Servant or Rider
    • Suggested Servants: Zhuge Liang, Rider Servants

A team comprised of Riders can easily dispatch the waves. The Golems should be targeted first as they are Berserkers who can deal heavy damage to your team. Ideally, we should have a ST and AoE Rider in our frontline, as our tactic is to build up NP on the first waves then use them upon the final wave.

One of the more straightforward Bonus battles.  A team of Sabers or Sabers and a support servant like Zhuge Liang will clear this battle relatively easily. One AoE Saber and one ST Saber is recommended in the frontline. We charge our NPs on the first waves the unleash them on the final one.
