Iskandar worked for me, but I guess you can replace him for the strongest AoE you have and it should be fine still.

During the first 2 turns, eat the weakest mobs available while filling your AoE NP gauge with Arts chains.

In the 3rd turn, Gazer and Basilisk must be on the field, then you buff your AoE enough to kill both of them while being careful not to break Alter's first gauge. Your AoE NP gauge should be back to 50% thanks to Gazer's buff.

In the 4th turn, with a Door and Spriggan on the field, fill the remaining 50% of your AoE NP gauge with Waver and Merlin and blast through everything again, breaking Alter's first gauge in the process.

With this strategy, you reduce 6 from the 17 turns needed for Alter's hunger debuff to come in.

Finally, stall as much as possible with whatever Servants you have on the backline.

Even though I made some mistakes along the way, I think I cleared the quest with a bit of clearance as Cu and Herc were still kicking when I finally defeated Alter. 🤔
