FGO Summer Event "Death Jail Summer Escape" - Ishtar's Treasure Level Up on High Difficulty! [Strategy Diary

The "FGO" (Fate/Grand Order) summer event "Reprint Death Jail Summer Escape" was held from July 4 to 13.

I am writing this diary on the 13th, the last day of the event, so I hurried to finish what I had to do in this event.

In most of FGO's events, 4-star (SR) Servants are distributed.

In FGO, 4-star Servants are rare characters that are hard to find, even in gacha, and furthermore, Servants distributed in events have the advantage of having a treasure level of 5.

Originally, it was not possible to raise the treasure level to 5 unless 5 of the same Servant were drawn in the Gacha.

We would like to make the treasure level 5 for the distributed Servants alone.

Now, the distributed Servant for this event is a swimsuit version of Ishtar. I would like to raise the treasure level of this Ishtar.

In order to raise Ishtar's treasure level, I challenged a high difficulty quest!

In this event, you must complete a high difficulty quest to raise the treasure level.

By using a yellow star item called the "bright star of dawn" obtained from the high difficulty quest, you can purchase an Ishtar and multiply two Ishtars together to raise their treasure level.

And the party looks like this.
Yagyu Tajima no Kamimunori Munenori (Saber) and Nero Bride (Saber), both of whom have an advantage over Elkidu, the Lancer (spear).
And I brought Sherlock Holmes, whose skills are useful, such as producing critical stars and stopping the opponent's treasure.
All three of them have many Arts attacks that help them accumulate the NP needed to activate their treasure tools, making this formation easy to shoot their treasure tools.

First, increase the NP gain with Nero Bride's "Stars in the Sky A" and Yagyu's "Mukotori A".

By choosing Yagyu's Arts attack here, I would like to gain all of Yagyu's NP at once and fire his treasure tool early.

To my surprise, in this one turn alone, I have accumulated 92% NP, and I am very close to being able to fire the treasure at 100%.

On the third turn, I was able to launch Yagyu's treasure tool. Things are going quite well.

After that, I chose more and more Arts attacks, so Nero Bride also accumulated 100% NP.

Nero Bride's treasure was also triggered, and it did a lot of damage to Elkidu.
After this, thanks to the collection of Servants with many Arts attacks, I was able to fire Yagyu's treasure twice and Nero Bride's treasure once.
The treasure tool does many times more damage than a normal attack and has additional effects, so just being able to fire it repeatedly is an advantage.

With the amount of stuff in the treasure trove, we cleared the quest successfully. I got the bright star, which I needed to purchase Ishtar.

Summary: Servants with many Arts attacks can string together a treasure trove if used well!

We were able to successfully raise Ishtar's treasure to level 5 after completing a total of 4 high difficulty quests like the Elkidu battle.

This time, the party composition was solidified with Servants with many Arts attacks, which allowed me to quickly accumulate the treasure tool.
In addition, skills such as increasing NP gain made it possible to fire the treasure at once.
Servants with many Arts attacks are very strong, as they can hit the treasure tool repeatedly if they devise the right skills and composition.

Please try to use them with ingenuity!
