[Fate/Grand Order NA] Grand Nero Fest 2023: Nero challenge quest w/ Support level120 NP5 ArjunaAlter

I remember during the first run of this event five years ago in 2018, I was stressing all over this challenge quest during a particular lunch break
Now I just 3-turned it with my overpowered level 120 NP5 Support™ Arjuna Alter kekw
I initially tried Spartacus as DPS since his NP ignores defense, but eh, his damage was underwhelming. I then tried Emiya for the same reason, but couldn't get him to kill the Lancer Artoria Alter in the first wave due to type disadvantage. Tried Astolfo next, managed to kill the five enemies by turn 2, but only one of Astolfo's facecards appeared in turn 3 so I couldn't kill all of Nero's 3 Guts by that turn and had to go into turn 4
I then got curious as to whether Arjuna Alter, the premium DPS, would be able to do it. He cleared the post-nerfed version in 3 turns without any difficulty at all, and I proceeded to the pre-nerfed prototype version, and cleared it in the first try. Yup, Arjuna Alter is overpowered. Especially my level 120 NP5 Support™ Arjuna Alter one
